Another thing I forgot to mention is that you might notice in the video above that I have printed the entire shell, including the separate plates on the back. I made little 'guides' on the front plate so that it kind of 'pops' into place. It will still need glue though. I looked into making it possible to open the unit again at a later date, but there simply isn't room for functional screw fastenings. There IS a type of resin that could be used for 'living hinges' and a more functional 'snap together' assembly, BUT I have not tried it... and I haven't been able to get any solid data on how it holds up over time. (And there's a startup cost of maybe $550 just to be able to start experimenting with it!)
