54mm to T2 Adapter

thingiverse

Many commercial filter wheels have the side to the telescope equipped with a 54 x 0,75 threaded hole with a coupling ring to accomodate a 2" nose. Here is an adapter 54mm to T2 (42 x 0,75) allowing the wheels to be mounted directly to a telescope T2 backend. I printed it with a resolution of 0,15 and 40% infill and it is perfectly working. Depending on the material,a 0,10 resolution could be better. When coupling it for the first time to a metal counterpart, screw it carefully to avoid misalignments that could damage the plastic thread. Some little force could be necessary, but after some work everything will improve and go perfect.
