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.

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.
