small and light Double Gear Extruder

thingiverse

I'm currently working on a V2 which is significantly easier to handle and install. This is my first version of a double gear extruder that's extremely light and has a small footprint. I've designed this Extruder specifically for these AliExpress parts: https://www.aliexpress.com/item/4000404170721.html https://www.aliexpress.com/item/4000021186440.html https://www.aliexpress.com/item/32870078897.html The Noctua NF-A4x10 FLX works well! I use this Part-Cooler https://www.thingiverse.com/thing:2121279, which may be a bit low to be comfortable above the surface. My holder broke so I glued it with fire a bit higher, and it works well now (V2!). You can use another Part-Cooler; you need to try. You can use standard LM8UU Bushings or these ones https://www.thingiverse.com/thing:2121279. You'll also need an M3 threaded insert for the clamping part. I don't know and I don't care if other parts may work, but these do! I've got a V2 in the making and will update as soon as possible. I have no flaws printing PLA and TPU; I haven't tested other materials yet. You may need to widen some holes or tweak other things a bit, but mostly it should fit well. You may need the Filament guide for TPU; just hot-glue it on top of the Stepper (gonna change in V2). IMPORTANT INFORMATION: Assembling these Extruders is quite hard and may require multiple assemblies and de-semblies until you've got everything in place with the right sequence of assembling. If you don't have a variety of M2 and M3 screws, don't try. I'm gonna include a manual in V2 as well. All in all, it's a bit fiddly to assemble and one or two things may not be ideal, but it has no major flaws and is definitely better than my older direct Drive Extruder. I also think it's better than other double gear extruders up to some point. Comment if you have any questions or need support!
