1" Scope Ring Mount
thingiverse
made in tinkercad as modeling practice, can be used to hold anything about an inch in diameter. uses m3 hardware, the rings use x4 m3x20 and x4 m3 nuts, the rail mount uses x1 m3x30 and x1 m3 nut. depending on your printer quality you may have to ream the holes to size. feedback much appreciated. but seriously, just go buy some proper metal rings. don't expect to hold a good zero.
