I made similar 3d printed brackets. But I direct drive the focuser with a coupler and use microstepping to get the resolution - much less backlash.

Hi Chris,
I've been considering going to direct drive as the resolution is so fine on the 10:1 it takes a long time to move any real distance with the focuser.
They reference distance the draw tube moves per step and I'm at about ten times the resolution they recommend. which is just overkill and slowing the system down. Probably should of done the maths before I designed the mounting system
Did you direct drive to the 10: 1 reduced shaft or the standard one?
and being direct drive what stepper motor did you use? Nema 17 or something smaller?
