Fan mounts for sjkelly's dual carriage

The excellent sjkelly's carriage has mounting holes for two 40mm fans pointed towards the nozzle with a 45° angle. I actually needed to point fans towards the Budaschnozzle heat sink because of problems when dual-printing with PLA. So I designed this L-bracket.
