2Pcs Mars 3 Resin Tank Covers 3D Printer Vat Lid Accessories Protect Resin Kits for Elegoo Mars 3 Mars 3 Pro

This does do what it's supposed to do. I was expecting to be able to just take the lid off of my printer and set this thing on and it would cover it. Thats not the case. The screws have to be removed from the resin vat and then this thing just sits on top of it. It doesn't even sit on it very snuggly but sort of rests over it and if not carefully balanced by me it rocks to one side and doesn't completely cover it. That aside, with those considerations, it does cover the tank and should prevent the curing process in the vat.

These covers fit as intended, however I wish they would fit over the vat when the screws are still on. They’re really designed to sit on the bar after the screws are out
