Testing file for other to work with. Measurements are close. Printed it in Resin to test a printer, but it shrank a little (or have accuracy issues with the MP Mini SLA).
This is a mock up of the Top Plate on the MP Mini SLA that clears the max Z Height and can support a longer Lead Screw. For the stock set up you will need some kind of a "hat" on the lead screw. Its on my list of things to make next.
