It is build for ELEGOO Mars metalic resin tank.
Each level is 2.5mm high and equals approximately 33ml (37g).
The big jump is at 15mm which corresponds to about 200ml (220g) and in my opinion should be the upper limit when the pressure plate is raised.
Since during printing the plate and the print object is raised and lowered, one can not expect exact values therefore the whole is only intended for a rough assessment.
If you like my design I would be happy about a small tip. ;)
But most I would be happy about a Make Photo post.
