SCORBOT Ru4 Encoder Wheel

This replaces an encoder wheel on a SCORBOT RU4 robot Pittman motor. The openings are a little deeper than the ones on the actual machine. The original encoder wheel is held to the shaft with a 000 set screw; this model is a press fit. It needs to be printed in black or the encoder won't be able to distinguish the slots and it will read poorly. The encoders used on the robot no longer are available for purchase so this appears to be a viable solution for those of us still using these educational robots.

The picture I uploaded is the encoder built on an M3D using their carbon fiber filament. While not beautiful, with a little work with a file and razor blade, we got it to work. We printed a couple on better printers with better results, however, we don't have black filament at work so they would need to be painted before using.
