I'm feeling really good about my new LED art project. This is a collab with my partner Allie who did the illustration/vectors for the cloud. It'll have LEDs going under both layers, and then white opaque vinyl on top to give it a crisp edge and hide the coroplast ribs.
Per usual, this was designed in #inkscape and the inner layers were computed from that using #OpenSCAD. #ledart
Reste le couvercle de la trappe du câble secteur qui manque, rien de bien compliqué avec #OpenSCAD, pour le jour où j'ai un filament de la bonne couleur (ou proche, faudra que j'en trouve du rouge ORIC tfaçon).
One of the current book bundles at HumbleBundle contains 3 books by John Horvath and Rich Cameron featuring #OpenSCAD for visualization and examples (among 15 in total with various topics on electronics and robots).
cmake:1, Iris:0. I have given up on compiling #OpenSCAD from source .... for now.
But in the meantime, I've got a binary installation running fine and I think I've got a good start on what I wanted to do with it.
I'm working on a puzzle version of the periodic table of the elements that encodes the angular momentum quantum number (s/p/d/f) in the shapes of the pieces, increments in layers for the principal quantum number (shell number), and can only be assembled in the correct order of electron filling. I'm pleased with the concept so far. I'm going to have to be clever about how to enforce order of assembly, but I have a few ideas, and it'll probably take iteration at the printing stage to get that part right.
Big thanks to @jcorbin for walking me through a ton of finer points of #openscad I've made my first #3dprinting model!
It's a little late for indie bookstore day but these are bookmarks for my local bookstore.
I'm testing a print in the only color PETG I've got, and will try a 2 color PLA in the morning. I think the inset one would look really good with the letters (and bottom of the bookmark) in black with a white top. 🤔
While you can't directly grow a volume from an unclosed path in #OpenSCAD, you can fake it by doubling the path on the way back with a little displacement…
shape_delta = [0, 0.01];
shape = [ each path, for (i = [len(path)-1:-1:0]) path[i] + shape_delta ];
Then you can:
linear_extrude(h) offset(w) polygon(shape);
edit: it might not work for all paths though, YMMV.
Tor prosty, długość to 16LU (lego unit, 16mm) podwójny zwykły prosty, czyli 256mm (a z wypustkami dodatkowe cm), dzięki ułożeniu po przekątnej da się ;)
Na zdjęciu numer 1 leci testowy wydruk jednego krótkiego toru wg poprawionego designu oraz 4 płytek łączących tory lub pozwalających budować coś obok nich ;-)
Zdjęcie numer 2, to tor, który drukowałem od spodu.
Warto podkreślić, że robiłem wydruk bez podpór na całej długości oraz z niestandardowym ustawieniem "bridge angle".
Czasami brakuje mi precyzyjnych ustawień bridgowania.
Also, I dumped this publicly some time ago and didn't say anything about it, but:
Should you need #openscad models with accurate dimensions for various storage form factor devices, such as a 5.25" full height drive, or a 5.25" optical drive, or a 2.5" internal HDD, with a variety of connector locations, all direct from SNIA's online specifications, I got you:
Two #openscad models of a 3.5" internal hard drive, top and bottom. The bottom diagram is spun 180-degrees on its Z-axis, showing a carved out SCA-2 connector.
Straight Duplo track of 12 duplo studs, equal to about 120 LU (Lego Units, one is 1.6mm).
We (me & son) need them to build looooong bridges ;-)
This one is a test run. If it works more or less ok, i'm gonna print few more.
It was generated and fine tuned from a OpenSCAD model available on Thingiverse.
I have my own brick OpenSCAD script, which generates better print models, but my script is inferior in parametriztion and it's not that easy to integreate it.
It presents as #OpenSCAD which I love, only you write #Python instead of that C-ish stuff it uses, and if I read correctly it's got a better underlying render engine. Only heard about it because someone did a #Gridfinity reimplementation with it, and all things being equal I would definitely rather use that than devil-begotten, temple-beridden, snot-encrusted #Autodesk products.
I want to 3d print some button housings for tactile switches - the simple toggle/push buttons we see everywhere in electronics kits...
I actually eventually want to design something for one of those cheap matrix setups to go in.
So this morning I'm off to see what I can find, but if anyone already has an #OpenSCAD design that they can recommend with a good mechanism and mountings I could use as a starting point, I'd be very interested in hearing about it :)
Ok. so this is where I'm at for the moment for a test print just to see if spacings/etc might work...
This is literally just for button spacings. I'd want to extend the outer box to enclose the whole thing and ideally support the mounting holes and things too at some point.
But its a start and it is all parameterised so should make accommodating different arrangements not too tricky!
