Thread adapters M42 : T2, camera filter 52mm 55mm 58mm

Here I start dumping the 100+ STL of screw thread adapters that I've made for the Telecentric project

Waiting for the famed OpenScad “universal adapter” Maybe I'll put them all here. Start with some M42:

Camera mount thread M42x 1

• adapter for the T2 (42mm x 0.75) M42-T2  and T2-M42 , Female-male, 8mm high.
• adapter to Objective filter thread (52, 55 and 58mm, x0.75) Female-male only
• Only M42, one Male-male long, one female-female short, two M-F with long female and long male respect
• Some aperture stops that screw into M42, so you can use the previous Long Female as aperture tube.

All designs published here have been printed, tested, tweaked, reprinted, redesigned from scratch, printed again, should work fine…   Corners chamfered, smooth thread start and end, special thread design for 3D printing.

The 2D construction drawing with quotes, no, that's too many designs.

 I'll go looking for some more photos of makes.  Print fine and slowly (0.2mm or better less)!   No raft please!   No supports! All print from the female down, sorry orientation of the STL is sometimes random.   Black! Don't do like me with whatever color.

All prints have been made at Sølvberget bibliotek
