Project Overview: Enhancing the Prusa MK3S+ Extruder with Geared Design
This project is converting the Prusa MK3S+ extruder into a geared extruder configuration. The primary goal is to harness the advantages of a geared extruder while retaining compatibility with as many of the original stock components as feasible.
Some new parts are required:
- Bondtech RIDGA V2 https://www.bondtech.se/product/oem-ridga-reverse-integrated-drive-gear-assembly-v2/
- Stepper Motor - LDO-36STH20-1004AHG (XH)
- 1 off M3x10 Cap head screw
- 1 off M3 Nyloc nut
- Printed parts in the files section
Notes on printed parts:
Materials that have been tested so far: PETG...
Some of the components do have overhangs and need supports
When printing the parts in PETG I use PLA as a support interface with:
Top Z distance = 0mm
Top interface spacing = 0mm
This gives a good quality finish on the overhanging surfaces
Assembly Guide:
Update required - The step file shows the orientation and alignment of the new components. Otherwise the assembly steps are very similar to the stock extruder
