The front wheel of my roomba is wearing out and I need a new one.
For it to work properly it has to be half black and half white. Since I do not have a double extruder, I have designed two separately printed halves that can be joined together to form a complete wheel.
I have remixed a previous design. https://www.thingiverse.com/thing:980448
Black and White
For a better result, print it on a 97% scale, fits better in the hole of roomba.
Sanding and Glue.
Sanding the sticks a little so that they enter into place. it is hard because of how small they are.
To join both halves I have used contact glue
