i needed a simple way to clamp in an axle. First i thought - magnets! But then I thought, compliant mechanism!

I wanted a different mounting system to hang my filament rolls in my dryboxes, so I could rewind them with a magnet.
Since I already had some axles from a previous build ()https://www.printables.com/model/1249376-the-ultimate-cereal-container-filament-drybox), I made a compliant clamping system to mount the axles from that build into the new system.
Since it is compliant, you can just snap-fit the axles and swap out rolls easily.
I went through several (6) iterations to get the best possible proper clamp. Holds a min. of 3kg per clamp (tested with a small dumbell).
M3 nuts are press fit insertable.
Clamps a 608 bearing exactly.
M3 10mm bolt is flush with the m3 nut on the inside.
Built in spacer to prevent bearing from touching the side.
Can also clamp an axle with diameter of 608 bearing. (but bearing slides a bit more easy).
Use PETG (always prusament ;) ) and 25% grid infill.
