Plugs up another big opening in the rear (20.5mm diameter effectively) and still allows cables to pass through.

*** Thanks for checking out this model! ***

*********
This opening is another source of hot air leakage - it's as big as a 20.5mm hole! Covering it (and others) up is part of a bigger project of mine to plug up ALL the sources of air leakage so the enclosure can heat up faster and max out at a higher temperature even without active enclosure heating.
Features:
Simple one part cover that snaps in place.
Installed from the inside so you don't have to disconnect anything to install it.
Prints quickly and without supports.
Comes in 2 Variants:
The “1” variant accommodates ONLY the accessory power cable for Prusa's LED Light Strip / Advanced Filtration System.
The “2” variant accommodates the BOTH the accessory power cable and a standard 5.5mm diameter(6mm max) jacketed Ethernet cable.
NOTE: Do you want a "blank" one that blocks anything from passing through? Click here:
Recommendations:
Use PETG/ABS/ASA. Tested with Polymaker ABS Black.
PLA is not suitable for the function of this model - it's not great at resisting higher temperatures and will take a set over time and start loosening up.
0.2mm layer and 0.4mm nozzle works fine.
Use textured Prusa print plate to match the texture of the enclosure.
Installation:
First, insert and align the catches next to the cable opening.
Push down and towards the LEFT side - firmly - to snap it in. Be careful that no cables are pinched before you snap it in place.
That's it, you're done!
For best results with heat retention, I suggest you download and print my other designs as well:
