Document information
Experimental repo for building openscad files into different outputs.
This is still work in progress but can already build a png and stl of each scad file in the opescad directories.
See the online or pdf versions for the images as the readme is realy only the source and right now is not WYSIWYG!

VacuumPCBbase - 3D Object
The base for the PCB to sit on in the Box.
It’s needed to raise the PCB so that the Tubes are on (better) display out of the top of the lid.

VacuumPreAmplifierBase - 3D Object
housing a retro vacuum tube china preamp.
Have a nice wooden box that is looking for some use as a housing The pre-amp is a cheap vaccum tube type sourced from aliexpress https://a.aliexpress.com/_B0MVMZ
I’ve created an openscad model of the Box based on some measurments with a calliper. The model is designed to help asses where to drill holes and to print a guide to drill the holes. The preamp has a power input (12v~) an in and an output (headphone jack) and a Volume potentiometer. Also the housing is to expose the Vacuum Tubes to the interested viewer. Since the lid is hinged and the relative position of the tubes to the lid, when opening, is difficult to eyeball the model was created to try out different Hole placments as well as providing a template for Drill guides.

Howth-cieling-spots - Project
The spots for the ceiling in Howth needed replacing and the replacement spots had a few millimeters too little radius so that they didn’t cover the hole properly in all places.
The lamp ring was a quick fix that turned out quite well and looks good.

Procedural weathered fractal terrain
by Alex Matulich, May 2021, updated with more Customizer sliders March 2022
On Thingiverse: https://www.thingiverse.com/thing:4866655
On Prusaprinters: https://www.prusaprinters.org/prints/129126-procedural-weathered-fractal-terrain-in-openscad
Generate a fractal landscape with an optional weathering erosion algorithm.
See my blog article describing the erosion algorithm here:
https://www.nablu.com/2021/05/simulating-erosion.html
At the moment, this script makes a square paperweight with a landscape intersected by a sea. It is intended, eventually, to be the basis for a model of a planet with continents and oceans.
There are several parameters that can be cusomized, explained in the comments by each parameter below.
The fractal terrain generator tends to produce mountain ridges and valleys aligned north-south or east-west. That's just a natural artifact of the algorithm. The ridges can change orientation slightly with more erosion.
*/
// ========== customizable parameters ==========
// maximum subdivision levels (max 8)
maxlevels = 7; // [0:8]
// Number of facets generated is 2 * (2^maxlevels + 1)^2.
// Therefore, 8 subdivisions generates over 130,000 facets, 9 would be over half a million facets, 10 would be over 2 million facets. DO NOT EXCEED 8. Eight is enough!!
// random number seed
seed = -1000;
// The landscape generated results from a combination of maxlevels and seed. That is, using a different value of maxlevels with the same seed generates a different landscape.
// Interesting seeds with maxlevel=7: 2, -1000, 8000000
// Interesting seeds with maxlevel=8: 2021
// length of a side in mm (default is 100)
sidelen = 100; // [50:180]
// z height magnification (default is 30)
zscale = 30; // [10:50]
// raise or lower entire landscape by this amount (typically 0)
zoffset = 0;
// number of weathering passes to erode the landscape
erosionpasses = 2; // [0:4]
// This is a slow process for high subdivision levels. The console window displays a count of the weathering passes being done.
// sea level (can disable the sea in the 'show' parameter next)
sealevel = -0.5;
// The landscape+sea object has a varying height above and below z=0, and it is positioned with the z=0 value centered at [0,0,zoffset] on the axes. Changing sealevel does not change the position of the object in 3D space, it just changes the position of the sea relative to the origin.
// render a box base for the terrain
boxed = true;
// If true, the terrain is rendered with a box base extending 1mm below the lowest point of the terrain. If false, only the landscape surface is rendered.
// what to render
show = "both"; //[terrain,sea,both]
// "terrain" renders the terrain only (boxed or not)
// "sea" renders the sea only with terrain subtracted from it. This is useful only if you want to print the sea profile on the sides of the box with a multi-color printer.
// "both" shows a union of the landscape and sea together.
// The easier way to make a different color sea is just to print the combined model, setting the slicer to change to a new filament after the top sea level layer is printed.
// bevel off mm from the corners (applies only if boxed==true)
cornerbevel = 6; // [0:20]
// corner elevations; suggested range -1 to +1
cornerelev = [[0, 0], [-0.25, 0]];

desk - Project
fastener - 3D Object
This is a fastener for a writing Desk.
The idea is to add a magnet to hold it up and to print it so that it does not require a bearing.
-
V1 is the first prototype for a first print test and fitting test
-
fits well and axle didn’t print free so need update
-
The reason was that the axle required supports winside the part to build
-
Changed the axle to 45 degree angles to negate the need for supports
-
-
V2 added a better axle but didn’t get printed
-
V3 added a better cutout and is printed
-
The cutout is currently a dummy pending getting the axle to work to try it out with magnets taped into place
-
axle prints freely so moving on to screw holes, magnets, and covers
-
-
V4 Added final OCD logo and screw caps etc.
-
Mounted and working.

case - 3D Object
A case for an odroid handgeld console and accessories.
The edges are rounded and there are cutouts for the parts that protrude from the console.

openai - Project
I decided to have a go to see where openAI’s chatGPT has its limits.
And it does have limits.
It’s intersting to see that while it seems to know what an object might consist of it has a very hard time making the onject in any way accurate.
In any case it’s Interesting.
esp8266case-chatgpt - 3D Object
This one is also interesting in that it does some difference etc but it’s really not a model of a case.
It looks like it get’s the basic premise of subtracting one thing from another etc.
On the other hand it doesn’t seem to have a clue about dimensions.
Either way an interesting experimt which shows up the limitations of GPT models.

// Create the base of the case
translate([0, 0, 5]) {
cube([30, 20, 10]);

cube([30, 20, 10]);
translate([15, 10, 15]) {
rotate([0, 90, 0]) {
cube([30, 20, 10]);
}
}
}
// Create the lid of the case
translate([0, 0, 25]) {
cube([30, 20, 5]);
translate([15, 10, 25]) {

}
solar-generator-chatgpt - 3D Object
This is also an interesting experiment.
I asked chatGPT to make a solar generator openscad model and this came out.
On the other hand it seems to be good at figuring out what should be part of a solar generator.
I’ll have to take closer look of what it did here and how hard it is to fix it.
This could be promising in total but right now it more or less seems to have hit a brick wall that seems to relate to dimensions etc.
In other words it’s good at creating a structure but not so good at understanding the physics of what it made.

projector - Project
Control-Electronics - 3D Object
This is for a motorized projector screen (3m wide).
The motor used is a:
-
60KTYZ 220VAC 15RPM chinese motor
The existing electronics (controls) are:
-
A bit dated
-
An ugly rectangular box of semi transparent hard plastic
-
Repaired (220V side needed resoldering)
-
Only have an IR remote control (that doesn’t work)
-
Have yanky up/stop/down keys that are not very:
-
responsive
-
nice
-
tactile
-
etc
-
-
An ugly shade of cream
-
have a nasty red LED thats always on
-
are Always on
-
and have a few other niggling cosmetic issues that would make a designer get sick in a bucket
-
Are in general just shy of rip and replace by a hair’s width
The screen is on an axle that is rotated by the motor.
The axle also rotates a lead screw that moves a plastic card left or right.
The card depresses either a left or right micro switch that cuts power for that direction.
Both end stops can be adjusted individually.
The electronics have NO knowledge of the state and instead just turn on the up or down power for a period of time.
The period of time is greater than the time to travel the distance between the end-stops.
The new controls have:
-
Two triple position toggle switches (220VAC)
-
Auto/OFF/Manual
-
Up/stop/down (when set to manual)
-
-
An ESP32 with wifi and two relays
-
One for controls power (NO/NC) that sequentially connects to the other
-
That turns the motor left or right (NO/NC)
-
-
-
optionally a status neo pixel for when in wifi mode (will bother)
-
optionally a mini Oled (might not bother)
The aim is that the new controls are placed right next to the screen and allow manual OR networked control.
The manual control requires either a long arm or a stick (and this is by design as it’s considered not the normal mode).
The wifi connexion is primarily MQTT.
The remote is through MQTT with an option of a web page… that may or may not materialize.
The initial housing is JUST for testing without getting electrocuted.
The fittings are to be moved to the final housing when I have the proper measurements in hand tp print it.
I have a further motor (with an offset axle) that I accidentally ordered that may also be put to use to raise and lower the projector.

lid - 3D Object
The original lid replacement I printed was needed to hold the existing blasted thing together at all.
The lid is missing a mount for the ugly box it’s holding together so that this is probably better than designing a mount.
Right now the electronics just hang around (in the box with a lid) and look and feel ugly (while working).
Did I mention that the original had developed a fault that was solved by re-soldering the 220V side?
The screen uses a 230V 60KTYZ motor (with a centered shaft and 15RPM).
The screen has adjustable end stops that are micro switches that cut the power to either up or down power.
The end stops are activated when the screen axle is rotated and then also moves the stopper left or right along a lead screw attached to the axle.
The electronics just need to provide power for a period x that is longer than from one end stop to the other.
The electronics do NOT know the state of the screen.
Maybe adding a current sense probe or two might help there…. or not worth the trouble.

crossguard - 3D Object
This is for a plastic play "Katana" sword to make it more like a "One Piece" "Gryphon" sword.
The tiff files are the original sword cross guard from both sides so as to extrude the mounting holes for the handle and the sword.
The idea is to go from scanner to tiff.
Then from tiff to SVG.
Then from SVG to STL.
Then in openscad to subtract te shapes from the crossguard and to send it off to Cura and then to octoprint.

Appendix A: To do
Right now the github source is not perfect as the readme does not display the images when viewed in github.
-
Add a readme in the directories or fix asciidoc to deal with asciidoc not showing in github
-
Split the build scruipts to handle scad/plantuml/asciidoc in separate steps depending on changes
-
The scad build already ony builds scad files that exist and is fed by find
-
Feed with a list of changed scad files instead of the more simple find
-
-
-
Add further process steps for the images like meshlabserver to do furhter processing:
-
Stuff (glass rendering, wireframe, mesh magic, stats, etc.)
-
-
Need to add subdirectories to pool projects together
-
build index for subdirs
-
need to make the scad build fit to the subdir model
-
add check for empty directory (no scad files)
-
only build scad files and only run container with scad files (empties ignored)
-
-
-
Add further optional scad steps
-
Need to add view parameters as options
-
Need to add animation options
-
-
Need to add text display option for each item
-
Allow adding photos to the objects or projects to show makes
-
investigate including a js or similar stl viewer for html
