Crumb collector

I recommend watching the video before designing the crumb brush.
Before designing this crumb brush, I researched existing solutions.
There are many aesthetically similar models like mine, but they differ greatly in functionality.
Previous brush models often fail to perform their intended purpose.
I started with the same concept but added a geared rotation system.
This feature has two notable advantages.
The first advantage is the brush's rotation speed.
In fact, the geared system ensures that with one rotation of the drive wheels, the brush makes three rotations.
The second advantage is the internal gearing.
This ensures that the brush rotates in the same direction as the drive wheels, thus not hindering but actually assisting rotation.
Furthermore, the use of an internal gearing reduces space and eliminates the need for a large container.
M3x4x5 threaded inserts are required for assembly.
You'll also need M3x5 countersunk screws.
I also recommend heating the TPU drive wheel to fit it onto the gear.
The small pin used to rotate the gear fits through interference without the use of glue.
You'll also need the two inserts included with the print to remove the crumb tray.
These will need to be inserted into the side cavities to remove the components from the case.
