FMA 180 / TPO 180 Nema 14 Autofocus

thingiverse

Here is an autofocus assembly for the FMA/TPO 180 telescope. I use it with the MyFocuserPro2 arduino based focus controller. The stepper motor mount uses two 4-40 screws to clamp onto the body of the telescope. You could probably use M3 but you may need to drill out the holes slightly. The ring gear and spur gear use M3 grub screws.
