Laser engraver rotary tool
thingiverse
A highly accessible and uncomplicated rotary attachment for laser engravers, built using conventional reprap components. Two NEMA 17 motors are used, connected in parallel for optimal performance. The unit is constructed from 1/4 inch MDF. This simplified design allows users to easily customize and modify the assembly as needed. By employing two motors, belts, gears, or unnecessary complexity are eliminated. A helpful tip: adjusting the roller sizes on the threaded rod (either printed or cut) to match your Y-Axis gear pulley diameter will avoid modifications to your steps for the engraver. For example, my unit features rollers that are 0.85 inches in diameter. To learn more about this DIY project, visit https://www.youtube.com/watch?v=bCmKmEdohK4.
