I've recently bought a TL866-II EPROM Programmer to write out some ROMs for my recently acquired RC2014 Z80 computer. It comes in a cardboard box, and I was struggling to get everything back into it after a programming session. A bit like one of those tents you buy online, and can never seem to get them back into the bag...
Anyway, I've 3D printed a case to hold the programmer and the accessories which you can download from Thingiverse and make yourself:
|TL866-II in the case with accessories|
|Box and lid as printed|
