iRobot Roomba 800 & 900 series side brush

I designed this Side Brush as a replacement on my Roomba 980 but it should work on all 800 and 900 series Roombas.

This needs to be printed in TPU, anything softer like Ninjaflex will be too soft and the brushes won't do their job, anything harder like PLA, PETG or ABS will just snap.

I recommend printing with a dense support for the centre hole as shown in the picture, but it is not essential, it just gives a cleaner finish and allows the screw to fit better.
