am I angry and tired enough to do 3D modeling? this is the only time I can manage it.

I'M NOT A FAN OF THIS

and it's done printing. having a 3d printer that works is such a game-changer

that was clearly wrong. I've now fixed it.

dang it. it's too tight, I need more slop in the measurements.

naturally it now has too much slop and is loose in the enclosure

my two tips for designing things with 3d printers:
1. print small pieces. it's way easier to iterate on a part that you can print in 20 minutes than a whole big thing that takes an hour. Less waste, as well. now that I've got this button enclosure working well, I can just include this model into the larger design.

2. go get one of those multi-packs of nylon or metal screws and nuts. A lot of problems that are difficult to solve in 3D printing can be easily solved with "3d printing plus few m3 bolts & nuts holding it together"

I cannot recommend tip #1 enough though. Sometimes two minutes of actually trying to put together a part of your model is worth an hour modelling and measuring
