Elegoo Mars 3 and Mars 3 Pro Vat Tray

It’s great being able to buy spare vats for your Mars 3/3 Pro printer, so you don’t have to pour out the resin every time you want to change it for the next print. Unfortunately, Elegoo sells them with a top lid, but not a bottom tray, therefore the FEP sheet remains exposed to dust, light, and contact when out of the printer.

This is a simple tray to protect the bottom of your spare vats.

It is also compatible with my Elegoo Mars 3 and 3 Pro Storage Rack.

Important note: the outside wall is just 0.4 mm thick to make it flexible, but that means that you need to turn Print Thin Walls on in your parameters, or it won’t print.

I printed it with 0.20 mm layers, 30% infill, in PLA+ on an AnkerMake M5.

(Thanks to Rodrigo Souza, whose vat model included in his Elegoo Mars 3 model on Grabcad I used for the measurements of this design)
