The Final Version!\nM42 Lens to Canon EOS Body Adapter: A Remix of Three Brilliant Ideas! A huge thank you goes out to the talented authors who made this possible. It's going to take a little time before I can test it myself, but if you're feeling brave, please be my hero and give it a try! This adapter ensures a flange distance of 45.5mm, which is necessary for M42 lenses to focus at infinity (the EOS flange distance is 44mm, so it adds an extra 1.5mm). However, since I'm new to 3D printing, there's no tolerance on the dimensions. Don't worry, though - this adapter is designed to be printed using a Prusa i3 with Cura 3D software, where PLA material and High Quality settings (0.06mm) are used. So, what did I get from these three incredible designers? From @SkyRzn, I got the entire EOS bayonet, minus the extension tube - just 1.5mm of it! You can find it here: https://www.tinkercad.com/things/eZ0xn72o6Zj/ From @jeng28, I received the secure hole and index hole of the EOS flange. Check it out here: https://www.tinkercad.com/things/0lSVNIOYrTU/ And from @profhankd, I got the first 6 millimeters of the M42 screw - a real game-changer! You can find it on Thingiverse here: https://www.thingiverse.com/thing:132781 By the way, the EOS bayonet is procedurally generated in Python, resulting in a script for OpenSCAD that's a perfect fit (well, almost!) for stability. The program was written by @SkyRzn. A huge thank you to all of you who contributed to this amazing project! And special kudos to the person who tested the previous version and discovered that the procedural M42 screw wasn't quite right (see the comments). https://www.tinkercad.com/things/jI6Te3Pbb6Y Also, a huge thank you to @Noserider for making this work with just a slight tweak in dimensions. I'll make sure to update the files as soon as he responds to my questions. Oh, and did I mention there are some cool extras hidden inside the archive?
