I modeled the axle holder springs, which were the lynchpin of this project. I started with basic shapes, which I am sure I will update in future versions. I programmed an "exploding" effect to show the parts and how they will fit together.
The magnet fitted snugly in the loop, but the thread pattern on the shell and cap did not mate. I will update the thread pattern, and I need to change the springs, which were too thick to flex.
I added a viewing window to the shell for when I install a spinner. I made the spring half as thick as before, which made it shorter and should have made it more pliant.
The springs were 0.5mm thick and had gaps the same size, but they were too small to print reliably. The plastic fused with the nearby parts and was unusable as a spring.
I stopped trying to make complex spring structures in OpenSCAD and used QCAD to draft 2D shapes and extrude them as 3D springs. The process worked well, and I produced several variations with different thicknesses and spacings.
I printed four spring variations and selected a few to install in a case with axle pins and a magnet spinner. Unfortunately, the springs didn't prevent the axle pins from pointing off the sides, causing the spinner to sit unevenly.
The rest of the summary posts have been arranged by date.
