Installed LED bulbs and the factory dust covers no longer fit….so here we are.

Printed this in PETG, works well. DO NOT USE PLA, too much heat it will melt.

I used a .22 layer height on a .4 nozzle and it works just fine. 5walls/5top/5bottom and its completely solid, you can obviously go finer detail but it's not needed for this. Printed mine bright red and they really stand out under the hood :D

Its about 32 grams with support give or take, support only on bed so the clips that hold it are nice and smooth engagement. 

For some reason the tab engagements are NOT symmetrical so these do only fit one direction, same as originals. just swap the old o-ring and they work great.
