This is a simple remix of the Case found here: https://www.thingiverse.com/thing:1886598 by I_am_me.
I liked that the case was simple and had access for the header pins as well. The only thing that I have done to it was to put a mounting block on one side of it so that I could mount it directly to my Elegoo Mars MSLA Printer. Nothing else was done, and as such I left the file names alone. Please see I_am_me's thing to read what the numbers in the files mean.
I printed this so that both pieces fit the print bed's short side and centered. I accepted that a very small amount would not be printed and cut off. I also printed this directly on the Mars bed without supports. After curing, the PI dropped right in with no cleanup as did the top. I had to secure the top with a drop of super glue in each corner, the fit is designed for an FDM printer and not an MSLA one.
To mount this to your Mars you will need 2 x M3x8 Flat Head Socket Screws since the original screws aren't long enough.
