1/2 UNF-20 male to 1/2 UNF-20 male adapter for the Hatsan Jet I and Jet II.
Print in ABS/ASA/PETG for extra durability. 100% infill (or 6+ perimeters) with 0.15mm layers around the threaded part at least for a good fit.
USE AT YOUR OWN RISK! Test the adapter with any attachments, to make sure it can support the weight. This is a plastic part and layer adhesion is crucial.
