3D Prints May 2024

With a 3D printer, I feel I should catalog the things I've designed and printed this month. I imagine there will be fewer in general in the future.

Sliding-door latch cover

First was a cover for the sliding-door latch. The original one came off many years ago now. I think we found it but didn't know what it was. So it sat on the kitchen counter for months until we gave up and threw it away. Of course, it was only then that we realized it had probably been for the sliding door--which was now just a bit of bare metal. But not anymore!

Designed in Bambu Studio. I would export to an STL, but it fails due to self-intersections in the mesh. But it prints fine.

Curtain-rod hook cowl

The little cowl that holds the curtain rod in place snapped off many years ago and the rod has sat lying on the window sill since then. But, less than 1 cent later, it's back up and working again.

Kinfire Chronicles: Night's Fall organizers

My most ambitious project so far, I designed a set of organizers for the Kinfire Chronicles game. They stack in the box where the riser, loot box, and spacer foam originally sit.

Tan would work better for the color scheme than the yellow I used, but I didn't have any tan filament.

I designed this entirely in Bambu Studio and again had issues trying to export STL files. I started recreating it again in SolveSpace as a way to learn that program, but I haven't finished yet.

I had to take a detour to implement text kerning in the SolveSpace code base. I have an open pull request on that project to get the new feature merged into the application.

The cardbox models came out ridiculously large (96 and 10 MB each) when I converted them as much to meshes as I could. Hoping that won't be problem when I finish re-implementing them.

R/C Car Part

I bought an R/C car from RadioShack when I was in middle school and it's followed me around since then. Several years ago I pulled it out and let Heather drive it around. She ran it into a curb and a bracket that attaches the front-left wheel to the chassis snapped. Not really her fault, the plastic was just old and brittle.

So it went back on a shelf in the garage waiting for me to figure out a way to repair it. I tried a number of things, but nothing functional. It needs to hold a smooth cylinder for the wheel joint to pivot in, so I couldn't just glue stuff together.

I took this as another opportunity to learn how to effectively use SolveSpace and carefully measured all the parts and recreated the bracket. I printed two, making adjustments each time, before realizing that was a dumb way to fine-tune it. Especially since I couldn't actually see what the problems were. Instead I took a picture and overlaid it on the part I was designing to make the final adjustments (which were down to tenths of a millimeter).

That worked great, the part fit, and the car is back in business.
