Compact Cooling Duct for Monoprice Ultimate and Wanhao D6

thingiverse

A simplified and compact cooling duct for the Monoprice Ultimate and Wanhao Duplicator 6. Printed and tested, provides a good directed airflow with the point of extrusion directly centered when mounted. Does not droop over time like other's designs. Uses a small amount of filament and easy to print. Screw holes might be a little tight, so just wear them in prior to installing, something like the tip of a flat head screwdriver, tweezers, etc. Just insert until there's a bit of pressure then twist them around. Do it for both sides and the installation will be easy. Printed at 0.1mm with 1.2mm walls. Update: While this design performs better than any other users design out there, this is not my latest best performing design. This one is what I consider to be the best solution for the stock fan: https://www.thingiverse.com/thing:2499597
