Simple cover to keep debris out of your reservoir. This cover fits snug, matches contours, and doesn't wiggle. Shouldn't matter what you print with, it's not supposed to get wet or hot.
Printed here with Polyterra Army Blue Matte on a Mini with Prusa PLA Quality profile 0.2mm.
If anyone wants to remix let me know and I'll upload the f3d file or step.
