Norns Grid 128 Back Case

My bf wanted to make his gear lighter so he asked me if I could model a PLA version as the Norns case is very heavy.  BUT, big woopsie: It does not fit inside our BambuLab printer. Oh well, if you have a bigger printer, try printing this out. 

Note: Have NOT tried printing this yet. Also, I can't seem to replicate the hole for the screws in the 3D model as it is conical and is above my skill level - hence, I attached the CAD file for you to tweak.
