DIY Rotary Module for K40 Laser Engravers! HD

After many requests, I have finally put together a guide to make your own rotary module for your K40 laser engraver! This is a surprisingly simple build and will undoubtedly be the best accessory you will have for your K40! While there are 3D printed parts in this project, I have listed alternatives for those pieces so access to a printer is not entirely necessary. Please post below if you have any comments, questions or suggestions!
