Laser Rotary Attachment

thingiverse

This is a complete overhaul of a rotary attachment I discovered online approximately two years ago. The inspiration came from https://www.thingiverse.com/thing:1359528, which utilizes 2 steppers and offers full adjustability on both ends. I don't display the hardware, but everything uses M4 screws except for the motor mounts that support the Nema 17's steppers. I created a mock-up of this design in Autodesk Inventor and then used the model as a general outline, deciding not to build it exactly to print. The wheels are turned on my lathe using 1 1/4" aluminum stock with a small slot for the o-ring wheels. I simply selected two o-rings that fit and can no longer recall their size. The idler wheels are leftovers from openbuilds v-rollers I had lying around. The base is machined 1/2" Acrylic that I had left over from another project. I cut it on my CNC router. Next, I used my CO2 laser to cut the idler bracket and stepper face plates using 3mm black acrylic. Finally, the motor end and idler end supports were 3D printed using my Leapfrog Creatr printer. As you can see in the photos, I ran out of filament after the first print and changed colors.
