This is a remix to help everyone who has a Bang Good version of this 3.2 inch display. The buttons are slightly miss aligned from the Joy-It version. See: https://www.thingiverse.com/thing:2501678
Go ahead and print the base and buttons from the Joy-It version and use the two parts I've done here for the full case.
I've included the FreeCad models of the two parts if anyone wants to re work it further. Please upload your source files (not just the STL or AMF files!), keep at all truly open.
20% infill should be fine
