External Hero Me 5015 duct cooling

cults3d

Ultra light external cooling duct to prevent vibrations caused by 5015 blower. I wasn´t able to find any lightweight external cooling using 5015 blower (only berd air) so I decided to create my own prototype. V2 - Smaller nozzle cooling openings for increased cooling V3 - Bigger nozzle cooling opening for larger cooling surface (I personally use V2) Blower is attached by Cooling sleeve on top aluminium profile using 1x M3x30 bolt 1x M3 T nut 2020 I used gooseneck tube dia. 16x12mm (tube used for cable management) about 600mm in length. I also suggest to use softer tube. Cooling sleeve (mounted on top) weight about 9 grams of PLA. Cooling duct mounted on gantry weight about 14 grams of PLA. Duct is originaly created for Lotmaxx SC-10, but it should also fit Ender 3 and CR 10 without any issues. Created for Hero Me mount. Please leave a comment if modifications would be needed. I am still working on upgrades. *Added test of single 75 degree torture test to justify results. Refferences : Original Hero Me: https://www.thingiverse.com/thing:4460970
