This is the vat cover I use for my Elegoo Mars 3 printer. I couldn't find a cover that fitted perfectly the shape of the vat and decided to design this one. I added an Elegoo logo on the top.

It has 2 openings at the sides in order to leave space for the bolt heads. Thus, it is possible to cove the vat when it is still mounted and without removing the bolts.

The aim of the cover is to reduce odors and protect the resin from UV light and dust, without having to drain the vat.

I printed it in PLA, with 0.15 mm layer height and 15% infill.
