Slew Drive

thingiverse

This is the primary drive system for a Alt/Az GoTo telescope mount I am constructing. It utilizes a Nema 17 stepper motor to operate the worm drive, which provides a 15:1 ratio. Alongside 1/16th microstepping this enables a 0.0075 degree per step precision. All components were printed with ESUN PLA+, but they can be printed in any material. ##Required Components: * 1x Thrust Bearing [6655k61](https://www.mcmaster.com/6655k61) * 1x Ball Bearing, Trade 608 8mm shaft [5972K91](https://www.mcmaster.com/5972k91) ** I am confident that skateboard bearings will work as well, since they should be the same size * 11x M3 x 10mm x 5mm Heat set inserts. These are to attach the upper part to the lower part * 6x M4 x 10mm x 6mm Heat set inserts. These are to mount whatever you want to the slew * 4x M3 x 12mm screws. These are to attach the stepper to the drive * 11x M3 x 16mm screws. These are to attach the top and bottom part * 1x M5 x 20mm screw. This secures the gear to the bottom * 1x M5 nut. This secures the gear to the bottom * 6x M5 screws. These are used to secure the bottom to whatever you want.
