Lid (Dust Cover) for CR-10 Nozzle Holder

This is a lid designed to be used with the nifty nozzle holder by Frodotus (https://www.thingiverse.com/thing:2760208 ). It fits over his nozzle holder to protect the nozzles from dust.

It's held in place only by the friction from the tabs, so you can easily remove it with one hand. The edge profile is the inverse of the fillet on the nozzle holder to make the seal a little more airtight.

Wall and top thickness is 1mm. No supports are required. My CR-10 mini printed it in just under 30 min
