Community MMU3 Sliding Cover Plate

I’ve added a sliding cover plate for the community MMU3 version to cover the hole of the top part.
For the plastic part I’ve used part of a filament packaging. 

To fasten it, I needed to drill two holes in the top part and secure it with 2 M3x12 screws. 

After installing it, the chamber heated up faster and the odor (e.g from ASA) was reduced
