Update Universal Super Light HGT Extruder w/ NEMA14 36MM Stepper Motor Hardened Steel Dual Gears Bowden Direct Drive for Ender 3 V2 PRO 5 Plus CR10 CR10S CR6 SE 3D Printer

So this seems to be well built with tight tolerances. Needs to have more support for different hotends. I did find an STL for mounting in it with HeroMe7 cooling system. Also needs to have an actual attachment for a Bowden tube on the top as well. This would allow for use of a multi filament set up like the chameleon or ERCF from the boron group. I will follow with more info once I really get to run through the paces.

I have bought 2 of these in the past few months. I originally bought this for a Voron build but the shafts and bearings are different sizes from what Voron calls for. I have one of them on my Ender3 v1 in place of the original extruder. This extruder is really light and could be mounted as a direct extruder but I can't find a drawing to mount it as a direct drive.

I like this extruder and mounted it on top of the carriage for the Ender Max. Works good and is quiet and very light. Where are the prints they show in the directions? Why I gave it 4 stars.

This extruded and motor are very small and light. Seams to be working pretty good. Only have one print through it so far. Gearing ratio must be pretty high because my Esteps went from 97 to 708. Wires are pretty thin and all separate. I found that by twisting them a bit, they held together better. I’m using it on a Longer LK5 in a direct drive configuration. (Extruded mounted right above hotend).

Retrofitted onto an older Monoprice IIIP. Aside from having to re-pin the connector to my application, it works flawlessly. Steps/pulse required some fine tuning as it was drastically different than the original, but feeding properly now. Multiple mounting points made printing a new mount easy and additional hardware and heat-set inserts means retrofitting to anything should be a piece of cake. Value is great, time will tell on how long the servo motor lasts. Only needs would be separate part numbers for the servo motor and feeder gears in case of replacement, but the part is so cheap it may make more sense to just replace the whole Extruder if required

This ultra light extruder works great as a direct drive solution for the Ender 3, as the weight increase over the stock bowden setup is extremely small, and with an upgraded Creality Spider hotend, the flow rate is more than I will ever need on this printer. I have also experienced no slipping of filament even with materials such as TPU and TPE, meaning my printer can now print any material I throw at it. Extremely happy with the consistency, power, and weight of this extruder.
