Just wanted to jump in here give some cred for both the idea and the design. Very nice work indeed. I've recently started with 3d modelling and was recommended by a fried to take a look at OpenScad (since I'm a programmer). I don't regret that I did
love it. Picked it up really quickly and after a week or so designed the prototype of the Ncase M1 "tophat" (still work in progress). Don't own a printer yet myself, but my friend has the CR-10s with 50x50x50 print volume, one could make big cases with that thing
Also see you guys are talking about 3Dhubs. I've used them before, but recently they have shifted over to B2B only, so prices there could be rather high. I came across https://www.treatstock.com
they are basically what 3Dhubs once was. There I found people who could do prints for decent amount of money. But if you are starting to see the need for more and more prints, it would be better in the long run to just buy a printer.
