Testing V2 internal redesign. files will be here in the near future (Edit 14 sept 2025)

This is a remix from d3vilmastah's Diy harmonic drive mount, and i want to thank him for sharing his great design.
This is also an untested work in progress and may not work, an alt/az base and dovetail clamp are needed and further adjustments/materials .

I have adjusted the height of some parts to fit into a square 120x120x120mm aluminium tube with a 5mm thickness.

Materials (estimation):

5x Bearing 688zz 8x16x5mm
2x Harmonic drive size 17 with 1:100 reduction ratio and 8mm input shaft
1x Aluminium tube 120X120X120 5mm thick
2x 80t GT2 pully bore 8mm
2x 16t GT2 pully bore 5mm
2x nema17 400 steps 0'9 degree stepper motor
2x 186mm 6mm wide closed loop GT2 belt
2x 8mm shaft
1x Flysetc e4 board for onstep
2x motor cables
1x Everything i forgot to mention
