A simple Sanguino case with a fan and wire clamps for each side. No lid, open case type. The fan is offset slightly to the pololu and mosfets area.There are two versions: -the standard version with straight molex connectors (3mm clearance around the board) and -a wider version for 90 degrees angle molex connectors (17mm clearance around the board) which require more room around the board (files with "Molex90" prefix).Basically you only need screws for the board and fan only, all other components can be easily thermo-welded if you lack the required screws. Actually the board itself can also be thermo-welded with 3mm filament, if you bend its ends to hold the board in place. All holes are 3mm for 3mm filament.Print 1xBase 1xBorder and 1xFan Holder. If you find the wire clamps usefull, print 2xClamp also.The fan angle is adjustable and it will fit any 40mm fan. 12V rails can be found on the Sanguino boards, between the motor connectors.
