More than 35 years ago a friend made this turret for use with MTO 1000A (my design, material was PVC).
Unfortunately, he was not careful enough when machining the holes for eyepiece barrels, so all three are offset by ~3mm. Not a big problem for visual at low power, but because of this turret spend most of its life in the drawer.
I decided to 3D-print the more accurate version (I need to do only the rotating part), and for 4 eyepieces (it will be easier to balnce it properly)
To achieve the smooth rotating, I will finalize the inner surface on lathe.
