Shapeoko 3 Spindle Adapter - 69mm to 53mm

thingiverse

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/6hO2PujWrry This is a spindle adapter for my Shapeoko3, so I can use a Quiet Cut spindle in it. The SO3 has a 69mm opening on the spindle mount, and the quiet cut spindle measures ~52mm nominal. At 52mm, it was too tight, so I redrew it at 53mm. 52.5 would probably be better, I have to clamp the SO3's spindle mount all the way closed for this to be secure. I've included the Tinkercad link so you can customize to your own needs. Photos show my before and after spindle setup. The hose clamps were "temporary" which turned out to be about a year. It was nearly correct but looks horrible. The new adapter looks much better and the cuts with large cutters show no stepping in either the X or the Y direction.
