For the last couple of days I've been working on an #OpenSCAD program to create custom #Pantorouter tenons. Set the tenon dimensions, the inner bit/bearing, outer bit/bearing, rows/columns, and it does all the math. But after printing out a full size paper preview I think what I want to do is going to be much bigger than the Pantorouter can handle. #woodworking
@moira@NF6X I'm probably overthinking it. Who cares if there's a tiny dent that gets transferred to the tenon in the center? It’s just more space for glue!
@fozztexx@NF6X I... now that you say it, I think I've seen people do that intentionally. Have small channels, I mean. So you don't get trapped air and such. And similar reasons.
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
I'm improving the contrast of the lights by putting a layer of light block white vinyl on top of the coroplast. This test is showing me that it looks great, but I'll need to be careful as bubbles in the application of the vinyl are going to be hella visible with the sharp angle of the light.
Over the weekend, my partners and I finished getting the main body pieces and lights assembled for the light up cloud. I'm super pleased with how it's coming out - it's pretty much what I was envisioning (cloud design done by Allie).
Up next is finalizing the part assembly with VHB, routing the wires, and adding a frame so it can be mounted vertically. #ledart
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).
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.
@tca the result of the brush strokes looks awesome!
I noticed you lower the brush and raise only while XY are both standing still.
Have you thought about combining Z movements while performing a stroke?
Either to lower into a stroke, or to raise out of it.
