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

It's a brown boveri 2.5 kw servo motor with a 10 v /krpm tachometer. I'm
running a selema 1224 servo amplifier , at 100 dc . I still have some room
for more voltage but my transformer cabbaging skills aren't as solid as my
ability to find drives and motors. I may well try one of these for an index
This is astounding that it apparently works just fine.
It is a 3D printed part that adapts a stepper motor directly to a Sieg X2
mill. Just one part is required for the X and one part for the Y. It will
require 127 grams of PLA plastic which costs $2.47 My printer will take 9
hours to make

These were the winner in the opening comment. They have a five pack for
less than$20 which would leave 2 left over . Their mounting would work well
with a tone wheel on my spindle . My
Drive runs a tach and this would be a good solution
Gene,
Although they are often called "thread protectors" , I prefer to call
them adapter pushers.
I have found that their most important function is to be installed
BEFORE the collet adapter and to be used by turning CCW to push
against the collet adapter to remove it. Otherwise you will need
