Pulley for drawing robot

thingiverse

This part is designed for mounting rollers in a drawing plotter that utilizes 623zz bearings with an inner diameter of 3mm. The increased height and angled sides prevent the belt from flying off during operation. If installing the bearing proves challenging, scale the part up by 2-4% to make installation easier. When installing the bearing, three washers should be placed under the m3 screw for added stability. The build process is demonstrated in a video tutorial.
