Some #design & subsequent #3Dprinting for my #smartwatch, in a bid to tidy up my desk a bit. When I found my charger nice and hot from being magnetically stuck to some nail clippers, shorting out, I figured it was time.
Used #woodworking techniques for joinery, allowing me to evolve each piece to incorporate new features. A little dovetail in each joint with the back spine lets me swap out pieces, mix and match colours too.
Here's a little design detail I often use when designing things to fit snugly together in a 3dprint.
For joinery like these dovetails I'll put a few little "tension bumps" in the friction-fit area to optimize the fit. If it's too tight, it's easy to tune the bumps with an exacto knife or some sandpaper.
I tend to shoot for about 0.3 – 0.4mm clearance for a clear but snug fit.
Realizing #CAD tasks (#Blender) work well as escapism. You can lose yourself in such work, fully immersed in 3D design world, and hours will just fly by without notice.
Eventually I got a trial 3D print started and I've shifted back to a software integration task I've been neglecting. Made some progress there, so it wasn't a total escape today.
Turning my attention to supper now I think, while tending that rough first 3Dprint.
I design a lot of 3d models and share them online with CC non-commercial licenses.
It's really frustrating when folks download my work and sell it on Etsy, and tell me it's open source since they downloaded it for free. And then block me when I try to point out that not how it works.
And Etsy makes it really hard to enforce since they don't really care as long as they get a cut.
Finally got around to printing my frog chess set. I realized last night that I happened to have both blue and green PLA. (printed at 60% to fit a smaller board)
I'm thinking about printing a flip-down MagSafe iPhone charger to mount under the kitchen cupboard. This is kind of the idea. I'm still working out how to route the cord. I'm imagining magnets to hold it in position either flipped down or flipped up, but haven't modeled those either.
I got back to designing the under-cabinet MagSafe iPhone charger today. I got the magnets placed. There are three button magnets in the red inserts. Now I'm thinking about how to route the cable through the yellow block, leaving enough slack for free motion.
I got the cable management figured out and made the magnet cassettes and hinge work, and I printed it.
Sadly, the magnets are not strong enough to hold the flap in the horizontal position. And it doesn't really snap into the vertical position the way I'd imagined.
So either I'll come up with a better idea, or this project is suspended. Too bad, I thought it would be fun.
I couldn't let it go. I added two new magnets with better mechanical advantage, and now the flipper stays up.
Now I need to find some screws, model some holes for them, and print the pieces in their final material. I'm thinking matte black PETG on a satin print bed. And keep the magnet inserts in red.
I should probably remove the old magnet from the non-flipping part. It's redundant now.
Puh, what a ride. #Design of my #BambuLab lid riser with integrated ventilation, LED strip placement and support for the BL LED Controller has been finished. Now I have to print some parts. Then assembling, testing and I’m done. 🤓
Needed a cable organizer for a side table that has a support bar under the top and set back a few millimeters. I modeled part of the table, then designed a cable organizer that would fit the contour. Just snaps into place. No screws, clamps or adhesives. #3dDesign#3dPrinting
I think it's amazing how you can get from nothing to a fully parametric #STL of a toy screwdriver in eight lines of #Python code with #sdfCAD.
If I had tried the same in a graphical #CAD software, it'd probably taken me ages. Also, none of the buttery smooth curves the #sdf - based approach makes so easy.
Next week my DBH2 students (12 year old boys and girls) will take a Technology assessment test. We have been working on the design of elementary 3D parts with Freecad. Some of the tasks are very simple, others a bit more complicated.
As it usually happens with the rest of the subjects, there are students who are very good at designing and others who find it more difficult. The truth is that most of them have worked very well so I am optimistic about the results of the test. 🤞🤞
Jetzt ist die Frage, wie ich die Segmente verbinde. Eine konservative Idee ist, dass ich normale Kugelgelenke nehme.
Eine etwas innovativere Überlegung ist, dass ich Neodym-Magnete verwende, um die Segmente miteinander zu verbinden. Aber das ist vermutlich nicht ganz so stabil und das Innenleben wird deutlich komplizierter. Dafür sind die etwas "untypisch" für das Design verwendeten Kugelgelenke nicht mehr da.
TIL that apparently @FreeCAD can be controlled entirely from Python. The Python console that shows exactly what you're doing in the GUI is absolutely sick!
So can one replay a workflow from start to finish? Does that make a FreeCAD design version-controllable? Can the Python code be streamed to file?
