TRS-80 Model 3/4ish

TRS-80 Model 3/4ish:

I may have created a monster... There's one or two, maybe more, old computers in the house and my 14 year old daughter seems to have taken an interest in old computers too. More; she wants to build her own from scratch as, understandably, she doesn't have the same nostalgia for 70s and 80s machines.
So after some discussion we've embarked on on building a RC2014 computer together - a rather nice, modular, Z80 based machine that has a good deal of fiddling potential.

It occurred to me that it would be nice if it could be housed in a suitable case so I designed a TRS-80 Model 3/4ish box that she seems very pleased with - I'll also have an excuse to build that large volume printer that's been a box of parts for a while as I think my Anycubic Kossel Plus will struggle unless I cut the model in to an unfeasible number of pieces.

Size:
The .stl parts, as included, will either produce a small model, or pile of parts, that should fit just about any printer.
