[Emc-users] 3D Printed parts as the starting point for CNC conversion.

[Greg Bentzinger via Emc-users]

3D printed parts are a great way to jump start a CNC conversion.
I do think care needs to be used when making motor mounts. Steppers that run 
well usually run hot, and I do mean temps comparable to what the hot bed of the 
printer operates at.
One of the best uses of a 3D part is the ball nut holder. You can fit it up, 
grid some off, get the height just perfect and measure what the final version 
needs.
Items with thrust bearings - not so good. Most filaments distort under pressure 
- and that is at 100% infill.
Designs like the one posted is complicated - but designed towards 3D printing. 
That same motor mount could be made in simplest form with a single plate and a 
pair of standoffs. Again design by target method of manufacture.
