Vixen Super Polaris Nema 17 DEC Motor Mount

thingiverse

Remix from https://www.thingiverse.com/thing:3214768 Adjusted the DEC mount to attach directly to the telescope without need for the additional bracket on older style vixen super polaris mount. This eliminates the need for the extra bracket on this model, which many people do not have and can be difficult to find. The scope mount holes are intentionally snug to allow the 6mm bolt threads to bite into the plastic ensuring a secure hold. Just insert the bolts about 1 turn then press the motor housing onto the bolts until flush with the telescope body. Then finish tightening the 6mm bolts. This mount-box, and the RA mount-box from the original project are designed to use a commonly available 158mm GT2 belt, 6mm width. On my project I used a 5mm/16-tooth pulley on the motor and a 8mm/60-tooth pulley on the scope (with a 6-8mm printed bushing) which results in a 3.75:1 belt gear ratio. The original project used a 20-tooth pulley on the motor resulting in a 3:1 belt gear ratio.
