MPCNC, 52mm spindle mount

This is for the MPCNC and used to attach a 500W, 52mm spindle. The one I purchased was this... https://www.amazon.com/Spindle-Cooled-Milling-Converter-Engraving/dp/B01LNBOCDA/ ... but there are many nearly identical offers out there.

I tried a few others on Thingiverse, not bad but a few issues arose. Mainly I noticed the power cables slowly changing location. The spindle itself was rotating axially and possibly horizontally no matter how tight the mount was. Some also had large feet, meant for vacuum mounts and other attachments I don't need and just get in the way.

My lower mount has a platform for the spindle to snug up to which prevents sinking while in use. My particular spindle also has four M4 mounting holes on the face. The mounts platform has slots for those screws so the spindle will no longer rotate or shift horizontally.
