UPDATE
After receiving the board I tried putting it into this case. There are a few design flaws I should point out, and I will try to edit the file to correct them.
it appeared (based on the stl) that #6 machine screws were the correct fit, and that's what the case is designed for. however, upon receiving the board, i quickly realized a #6 screw was just a hair too big for the mounting holes on the board. I had to bump down to #4 machine screws, and thus the nuts don't seat properly (read perfectly) in the case. this is a purely aesthetic and very minor issue.
part of the base has to be filed a bit to make room for the power connector. this is also fairly minor and hardly noticeable.
lastly, and most disappointing, is the access to the audio and mic jacks. I didn't design nearly enough clearance for an 1/8" plug and cannot plug in any audio cable I own for lack of clearance. Thus, I cannot have sound with the board mounted in the case.
I plan to modify the bottom, reprint and test it. I will post the corrected part as soon as I can.
On the plus side. the square air vent in the top is just big enough to fit a fan directly onto the cpu heatsink (attached with #4 3/4" screws). and thanks to usb cable butchery and some soldering I have active cooling on my jaguarboard. The downside is it currently takes a usb port to power. I'd like to solder the fan power directly to the board, but I'm not sure where a +5v or ground connection point is, and did not see any detailed schematics available. can anyone point me in the right direction?
pics coming soon, as is an updated 3D print file.
