Yeah, the other (sneaky) reason for this post was to recruit the expertise of some of the truly amazing DIYers on this site. I'm a whiz at electronics, and have made tons automation gear for myself (auto-dosers, a koralia (12V) variable speed driver, dimming high power LED drivers, even a few robots) but a simple acrylic box that doesn't break or leak appears to be beyond me.
I blame my tools!
