Canon EF/EF-S to M42 adapter

Hi, this is a remix of the Canon EF/EF-S to M42 adapter, because I wanted to use my lens for astrophotography but couldn't focus.
Print settings:
Layer height 0,1mm
Supports: NO
#Note: There is no place for a locking hole, so try to print it tight.
#Note: It is easier to screw it on and off with a canon lens cap
