This model was 3D printed on an UP! machine, but should work just as well on a Makerbot, RepRap, or other such device.
Step 1: Necessary tools and materials
- 8x M4 screws (length of about 14mm)
- 8x M4 nuts
- 4x small washers to fit M4 screws
- available spool of plastic
The main tool needed is a 3D ptinter. However, the parts could probably be adapted to to work with a laser cutter since they are all 2D planar extrusions. Besides your tool of choice for the plastic pieces, all you should need is a screwdriver to assemble the claw.
Step 2: 3D printed parts
Washers are added where the "MainGear" pieces connect to further reduce friction.
The quantity needed for each piece is listed below:
