52mm Spindle Mount for MPCNC with Magnetic Dust Shoe

thingiverse

I'm working on a first draft for a spindle mount that's 52mm in diameter and can handle 500w of air-cooled power. It uses vacuum magnetic dust shoes, which are coming along nicely. One thing I've had to work out is keeping the lower dust shoe easy to install while still sealing properly with bits of different lengths. This design makes use of the four mounting holes on the spindle's face, which are 25mm apart and centered. To hold everything in place, I'm using six neodymium disc magnets that are 8mm x 3mm thick.
