Hero Me Duct (Fix for 'Screws Wrong Size') Ender 3 with Newer 4010 Fan and M3 Base Slots

thingiverse

This remix actually uses original screws. The base of the Hero Me Gen 3 takes M3 holes, and the Ender 3 duct provided by mediaman only fits M2 screws. This is a problem that my remix fixes. This duct can be mounted to the Hero Me Base (Gen 3) using M3 screws! This means you can use one or two of the Hotend fan screws to hold this duct on. **Warning: Be gentle with the base mount slot on the blower side! (See 3rd photo) While installing the duct, make sure not to bend or put pressure on it. I recommend barely snugging it up and tightening the left screw a bit more to compensate.** The better fix for our problem would be to print a new base with M2 holes instead of M3, but if you don't want to waste time/filament, this duct works great. Also, if your fan doesn't fit in the duct you printed, then you are better off with just printing this duct. Just don't break the right side mounting tab or it won't be worth it! Yes, thanks to cc70458, the newer style 4010 blower fans with larger tabs that Creality is using will fit perfectly! Remember to put the base mount screws on before attaching the blower fan. The blower fan still takes two of the original M2 bolts, but thanks to cc70458, they aren't needed since the fan fits really nicely and stays fine with just friction. In Cura, I had to scale the STL down to 10% for some reason, but it fit perfectly.
