Mechanical Laser Show No-Support Version

Edit: Both X and Y Cams updated with improved performance. Edit2: Noted a crucial omission in my initial design - added notches allowing the snap-together crank handle to move smoothly around. My slicer lacks support generation capabilities, so I opted for creative re-engineering instead. Now everything is support-free friendly. This design change also reduces printing time due to separated gears and cams. Print one of each part plus an extra Bolt.stl (I used 1/4" socket head machine screws). Remove the excess material around the hole on the bottom of the Cam(s). The X and Y gears should fit into the gear-shaped holes on the bottoms of the cams. Tolerances may vary. AdditiveTech created a fantastic design, and I'm grateful for their work!
