Whipped up a little case for a cheap SCR speed controller I got from trademe (same thing you'd find on fleabay though).
These speed controllers are pretty lethal without a casing as much of the board sits at mains voltage.
Lid snaps on - PCB pops in after removing the little metal angle bracket supporting the potentiometer.
Lots of ventilation to keep the heatsink happy.
Screw tabs are there to fix it down in a permanent installation.
As above, these speed controllers are a raw, mains voltage exposed board. They'll kill you (and it'll hurt the whole time you're dying) so be sensible.
I'm not responsible if you print one of these and still manage to get a finger, screwdriver or other conductive appendage in there (and subsequently do yourself some harm).
