K2 Plus chamber heater diffuser

I found that for tall (120mm+), heated chamber prints, the part can be affected by the chamber heater cycling on and off… I remixed the HEPA filter snap on covers to include some places for heated inserts, and a simple rectangular shield that directs heat up and down instead of at the part.  I'm adding a two pics of the testing, showing what a rear-facing part experiences to give you an idea.

HEPA filter snap on covers have tabs and holes for heatset inserts added, and a new shield part is added.
