3, 3D-printed focuser:

Lars had problem with his focuser, he designed a new focuser in CAD and 3D-printed the parts. The plan is to use the original draw tube, a 2" tube. It's to a 8" f/4 Schmidt-Newton telescope.

Lars B's comment:

The parts assembled, note the roller bearing that holds the draw tube.

Lars B's comment:

A video with demonstration of the focuser:
