Double MOSFETs mount
thingiverse
Tevo Tarantula Controller board cover is modified to accommodate two MOSFETs mounted on top. Controller board cooling fan is mounted on the reverse side. Horizontal slot at bottom for easy access to terminal screws. 40mm stands are for attaching a cover over the MOSFETS. Spacers are for extra clearance between the fan the the controller board (or use taller stands). Both E0 and E1 hotend outputs on my board died at the same time (I never even used the E1). With only one good output left (the coolingfan), I want to protect it. I'm now a believer in using two external MOSFETs. It is much cheaper to replace a MOSFET than to replace the controller board. Credits: The cover is based on one I found from https://www.thingiverse.com/thing:2372385 The slot is an idea I got from https://www.thingiverse.com/thing:1997377
