prusa i3 mk2 fan mods

thingiverse

at the moment just messing trying to get several things to mesh together.. mk2 done.. with a 5mm spacer on the hotend fan duct I think this will now fit . printing a test piece now and i have a 40x40x20 high output ,silent,fan to go on it.. OK this is mounted and working, printed it in ABS and it uses just the single screw from the original fan. You need to cut off the bottom of the hot end cover but now not only do i have cooling from both directions but I can see the nozzle clearly which I really like. I had to dremel off a tiny corner of my fan and duct on the left as that was easier than trying to make more of a depression into the axial fan mount. Obviously if you are still using the original 30x30 fan this is a non issue. clears the sensor , but only if you aren't using a protector.. added some photos of the mods actually on my prusa. credits.. fan spacer from here ( just modded to 5mm) https://www.thingiverse.com/thing:837532 axial fan mount remixed from here https://www.thingiverse.com/thing:2065461 fan duct from here https://grabcad.com/library/mk2_40mm_fan_duct-1 fan cover ... https://www.thingiverse.com/thing:2211780
