2023-07-28 (F) Weekly Summary

I ordered the wrong rods and had trouble threading them manually. I could not find replacements, so I ordered fully threaded rods. I fixed a faulty switch on my battery charger and got it working reliably.
Shallow threads

I received suitable M3 rods from Amazon and completed the assembly. I need to fix the magnet cover as it does not sit flush. The KeyRyptex is complete and looks good on the coffee table.

I'm miniaturizing the GrinderCompass using cylindrical magnets that I bought years ago. The parts need to be made on a resin printer for precision. I can make all the necessary parts myself for a working model.

I created a new model in OpenSCAD. I modeled the top and bottom with a hole for a chain on top and spring tension on the bottom. I added a spinner, pins, and supports for clarity. I made a GIF of the camera revolving around the compass and uploaded it as a video.

I opted for laser-cut plywood instead of resin printing for the GrinderCompass prototype to speed up the process. I sketched my design on my phone and changed the tensioning device. Scaling will follow the magnet's size.
Layer sketches

I changed my spinner mounting rod design in QCAD by adding a window to adjust tension. I will use a nylon standoff for the vertical structure, but I included a stack of M3 discs as a second option.
Drafted parts
