Anycubic i3 Mega Extruder Fan holder for heat creep prevention

thingiverse

I have my extruder motors control voltage set quite high to cope with skipping issues and I am already actively cooling my extruder motor using a 50mm fan attached to its housing. The extruder feed side however, especially the transport wheel and the lever with the press on wheel still get very warm. I want to use a printed extruder bowden attachment that is TPU capable and for that I need that side of the extruder to be cold as well. I attached a picture of a try that I had without active cooling. The part deformed during the first 45 minute print and wouldn't work anymore. This 80mm fan holder is clip-on and attaches to two holes in the side of the right Z-Axis carriage. it can easily be taken off while working on the extruder (feeding filament, for example). Use 2 coarse fan screws to attach the fan. You should be able to attach the fan from both sides, given there is enough room. There are probably much more intelligent solutions for this problem that interfere less with the print (especially if your printer is contained in a case, there will be a draft - I only print PLA and so far this wasn't a problem). Please contact me about any ideas or solutions you know. <3
