In the process of creating a vat holder (https://www.printables.com/model/638965-saturn-3-vat-holder), I needed to first make a simplified (simplified because the top is sealed and I did not measure nooks and crannies of the inside) Elegoo Saturn 3 vat, which I later used for a boolean operation.
You might also find it useful for other improvements or builds. Enjoy!
The author marked this model as their own original creation.
