Gripping gears
thingiverse
These gripping gears mesh with and rotate around each other, but with no axles and no frame. This version has "pass-through" holes, that allow a solid object (e.g. a screwdriver) to pass between the gears. YouTube video: https://youtu.be/RBZG8M8_a8Y To make these, you will need to print four copies of each of the files. Two of each file are bolted together using standard M3 nuts and bolts to make each gear. This is joint work with Sabetta Matsumoto and Will Segerman. Thanks to ICERM (https://icerm.brown.edu) for their hospitality during some of my development of this design.
With this file you will be able to print Gripping gears with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Gripping gears.
