Direct Geared Belted Extruder 1,75mm (v1)
This model has been superseeded for a V2.
New model has been turned 90 degrees: Direct Geared Belted Extruder V2 (1,75mm)
If you are looking for a bowden version, you should go see my Belted Extruder v.3 for 1.75 instead.
Key features

Gearings 1:3.75
Weight including motor: 316g - This is inclusive all gears, belt, screws, nuts etc..
Please note that a standard normal Nema 17 weights 290g in itself, so 316g is VERY light

Nema 17 used
I am using Nema 17 "pancake" as in flat model.
Manufacturer Part Number: 17HM08-1204S
0.9deg Nema 17 Stepper Motor 1.2A 11Ncm/15.6oz.in 42x42x20mm
I found it on german ebay.
You can reuse whatever Nema 17 you might have, but using a smaller motor dramatically decreases the weight.
Usage Requirment
While this Direct-Drive Belted Extruder 1,75mm (v1) has standard hole mount spacing of 23mm center to center of the mount holes, you are going to do one of the following 3 options:
Use a modified x-Carriage, which I'll provide soon.
Remove 1-2mm of the top of your existing Carriage.
Use a 8-9mm spacer-plate to put between your existing carriage and the extruder.
Buy one?
I am selling these. Also just the metal parts. Drop me a message if interested. I live in Denmark and can ship for DKkr 35 in Denmark, but let me know where you live, and we'll see.
3D model and files?
I do not offer up the extruder in other fileformats than STL, but you can see the model on MyHub on Autodesk's servers.
