Rubber Band Intake Wheel

This part was designed to be used instead of a gear or sprocket to hold rubber bands for a a robotic intake/ingester of small objects such as wiffle balls. (We found the gear teeth to be too abrasive on our rubber bands.)

In the current configuration, it has a 3.5" outer diameter, 8 fingers to hold elastic bands, and 1/8" square drive (Vex style). Two are required. The Solidworks (educational license) source file is included for your modification.

Update: We found a 75mm configuration
