I designed this small support to hold a couple of 40mm fan, the plate is made to fit aluminum profiles of a mendelmax 1.5! I'm using it as part of the cooling system of the electronics. UPDATE: User @Ubermeisters try it on his Mendel max 2.0 and it works!! Print it without support, I printed my out of PLA 3mm with a 0.5nozzle. 0.3mm layers/0.2 infill/ 2 top-bottom / 2 wall. It takes 20 min to print at 100mm/min. It's design to fit M3x12 socket screw to hold the fan, and M5x10 socket screw to be fixed to the aluminum profiles with a couple of t-slot nut. thank you!
