Dual Part Cooling Fan Mount / Shroud for Prusa i3 MK3S

thingiverse

Due to many people requesting this, I decided to remix the great model by jonathanrswift to fit directly onto the MK3S. Airflow remains untouched! Only the suspension was remodeled to enable direct use on the original MK3S. You just need to unmount the "Print Fan Support" and use that same screw to secure the new fan-mount in the same hole. I would suggest reversing the direction of the screw in the angled fan-support on the right; (slot for M3n nut is modeled) Makes assembly more easy! Use a M3 10 from the spare parts bag. (Foto) Don't forget to insert the M3ns nut in the slot (for the noctua fan screw) Prints without support when printed in mounting position. All other details remain and can be read in the original post of jonathanrswift who deserves all the honor for the design. Due to the fact that my "second" fan has not yet arrived, I could only test the "mounting" and the "single-fan-performance," which is interestingly quite good... UPDATE 22.June 2019 ------------------------------- Delivery of the second fan took longer than expected, but now it's here, and I could do extensive testing of the dual-fan-shroud. Here's the verdict: I am very impressed and very happy that I tried this thing! I've uploaded some more fotos for you to take a look. The FDM-Kickstarter-Torture-Test came out absolutely beautiful. All the "pins" just fell out of it when I took it off the bed. The spikes are 4cm long and "ruler straight." The 15deg overhang looks really good. Wow... https://github.com/kickstarter/kickstarter-autodesk-3d/tree/master/FDM-protocol Second is a lattice cube ( https://www.thingiverse.com/thing:1850320 ) To really challenge the fan, I reduced the size by 50%, making it only 60mm high and having only 2.3mm diameter rods. Last is the 55 to 85 degree overhang test ( https://www.thingiverse.com/thing:1564848 ) Only the 80 and 85 degree overhang did not really "look good." To recheck, I printed a 70 degree corcscrew, which worked just fine... All were printed using Amazon Red Basic PLA. The FDM Test and Corcscew with stock 0.2mm quality setting; the lattice cube using approximately 75% speed due to its miniature size. Greetz Rosy
