Hotend Fan Duct for Ender 2 Pro
Description
Second generation of my hotend fan duct for Ender 2 Pro. **Advantages:** - better air flow, - 4010 and 4020 fans mountable, - good view of the nozzle, - sturdy, - easy printing, - easy assembly. Print with heat-resistant filament, PLA is NOT suitable. I used PETG. No support required, just clean up loose strands with a knife. 3 screws M3x6 required. Please note that one screw has to be screwed in from behind (see picture above). There is a thread in the fan duct for this. If that is not stable enough for you, drill out the hole with a 3 mm drill bit and use screw and nut.
