The file 'Parfocalizable Eyepiece Turret (Ocular Revolver) 3D Printer Model' is (stl) file type, size is 18.2MB.
Four eyepieces can be used with this device, so that after rotation we can see a sharp image with any of them. This can be achieved by adjusting the eyepiece sockets to the appropriate distance.
Before you download the files and start printing, check if your focuser has a 48 mm back focus! How? Put the four eyepieces you want to use in the ep. revolver into the telescope, one by one, focus them - for example on the Moon - and then try to wind the focuser 48 mm inward. You should only start manufacturing the eyepiece turret if you have succeeded with all four.
The eyepieces do not need to be fixed in the socket with a screw, this is done by the leaf springs of the socket.
Important: The material must be PETG, otherwise the spring parts will not work properly!
