SLA PRINT VOLUME TEST

I wanted to test the print volume of my Mars, and liked the idea of having a tangible representation of it that I could hold in my hands. Particularly with the need to orient things in a certain way with resin printing, I like being able to compare the size of it to objects in the real world and even check for fit by putting an item inside the volume in whatever orientation I wanted.

I was not aware of any standard tests for this and wanted to familiarize myself with the capabilities and limitations of my new printer so I designed one myself. It has a few features to find the exact size of the envelope and demonstrate some of the capabilities of the printer (small features, thin walls, etc.). I made it almost completely open on two sides so it would be easy to fit objects inside. It prints flat on the plate and requires no supports.
Interestingly, I found the actual print volume to be a bit smaller than the 120x68x155mm advertised. I found the actual volume to be 117x65.5x15
