Model information

This adapter serveres 2 purposes besides the obvious one: The whole assembly of adapter and collimator can be checked for collimation together and it can also be collimated as one item removing possible adapter/collimator misalignment from the list of possible issues.

Printing and slicing

Make sure that seam on the 2 cylindric surfaces is in the prepared groove. Slicer should put it there by default. Otherwise a print seam that is protruding out  is going to mess up alignment in the focuser. 

Assembly

Assembly is press fit. Apertures are slightly flexible.
