After looking all over for a rotary axis for my diode laser, I tried a few on thingiverse, but none worked well for me. As I am not working on anything huge and do not need much torque, I decided to design my own direct drive Rotary Axis.

I cannot take all of the credit. Thanks to hexitex for his awesome 3d printable longworth chuck: https://www.thingiverse.com/thing:5791, I was able to make my design work.

While this did start out as a project just for myself, during the build process, I collaborated with nottingham82 on this project. Many thanks to him. Him an I both found different ways to improve the design, thus making a much better setup.
He called his a remix of my design, but mine is also a remix of his. Outside of the core base design, we each designed our rotary axis independently.

Please keep in mind, this was designed many years ago when I was a 3D design noob and was using Tinkercad. If you like the base style, look at Nottingham82's design https://www.thingiverse.com/thing:2561227. This design was a first for me for a larger multipart design to help me learn cad. It is not perfect my any stretch of the imagination. If i had design files to share, I would, but (again), this was done in Tinkercad. So, here is my warning.
THIS DESIGN IS PRESENTED AS-IS. NO EDITS WILL BE DONE TO THIS DESIGN. IF YOU WOULD LIKE TO EDIT OR REMIX IT, YOU ARE MORE THAN WELCOME.
