. Lead screw (worm) is 1" in diameter and 6 threads to the inch. I assume it is either square thread or Acme.
Please help me select a worm gear to fit. My intent is to print the gear ( once I find a CAD drawing) with my Prusa 3D printer. After all, it is simp ly a pointer with not much power being transmitted, ergo, ABS gear should l ast a while.
I might also try and design the entire mount out of ABS and print it. Alth ough it would not be difficult to do a couple of cross drills on a block of aluminum. One hole for the shaft with the gear, and an other for the moun t to the saddle.
All help appreciated.
