Was inspired by:  https://www.printables.com/model/438386-voron-stealthburner-led-diffuser-silicone-mold

Completely created within Prusa Slicer by importing a basic cube then loading the diffuser logo as a negative volume so it's a little rough. Prints fine but haven't tested it. 

Comments and feedback requested. I am just starting to dip my toes into the world of 3D modelling etc. and appreciate any feedback I can get.

Note: I am only uploading the file for the Rook logo as I left the source model untouched.
