50/30 Monoprice Mini V2 fan (50mm Hotend, 30mm parts)

thingiverse

This thing is a bit bulky but it works well. I wanted to use a 50mm fan for the hotend heatsink on my Monoprice Mini Select V2. The parts fan is only used for PLA so there is a little box on the side to mount a typical 1mmx0.5mm single pole slider switch. The little cylinder on the side of the 50mm fan mount is for a small capacitor (if your fan, like mine - does not like a PWM input, the capacitor is used to smooth it out to plain DC). I suggest printing in something like ABS or PETG since PLA might melt close to the heat block.
