MP Mini Delta basefan duct

thingiverse

Even after my last modification, I still wasn't satisfied with the noise reduction of the base fan in my Monoprice Mini Delta. I remembered what needed to be cooled at the base of these printers: it's the aluminum heat spreader, which is glued onto the drivers on the motion controller. This is why I designed a fan duct that directs the airstream from a more silent 5015 linear fan straight over the heatspreader. The duct is superglued to the fan housing, and the entire combination is secured with 3M mounting tape on the inside of the baseplate. It's in the right position over the heatspreader when you place the duct's marked corner 2.3 cm downwards and 2.3 cm to the right from the marked corner on the tin plate (see second photo).
