Alternative Ender 3 Hotend

The original Ender 3 hotend is garbage IMO, does an OK job with short PLA prints, very touch-and-go with PETG and PETG-CF. So I designed this "baby" compatible with Volcano ceramic cartridge hotends and older E3D-V6 kits. Hardly lose a print now, except where it's my fault or get lazy with levelling.

I use the standard 3010 fan-on-a-clip that comes with E3D-V6 hotends but, if you want to use the Ender 3's stock 4010 axial heatbreak fan, that's what the "duct()" module is for, adapting the 3010 clip to a 4010 fan.

The pink "bracket()" module screws directly to the stock Ender 3 X truck in the usual place, the blue "clamp()" module serves as a mount for the Ender 3's stock parts cooling fan. I use the standard 3030 fan, but there's a module to add a 4040 fan addapter.

I also have a module coming (you can see a prototype in one of the photos) of a parts cooling duct for the Ender stock centrifugal parts fan. I'll update the files once that maodule is added here. I was using the standard Ender duct, but it's garbage, too, really. The forthcoming one blows onto the part, directly at the hotend. I'm considering a dual head version with constraining nozzles to throw streams of cold air at high speed on the small spaces around the nozzle.
