Purge Bucket for CR10/Ender 3

This is a remix of the purge bucket by 3DMakernoob.
Instead of a brush, there is a slot for a 33x15x3mm piece of silicone.
I don't have the silicone mat yet, so I wasn't able to fit it yet.

To print better, I have also added a door that can be printed separately and then slid in.
Right now the fit is very tight, so I was only able to slide in the door once with force.
I might make the tolerances less tight, so the door can be slid out and in easily.

Might make sense to print this out
