The extruder can be tailored for specific pulley and idler sizes, spring length, etc. The latest source code is also available right here. Provided sample customizations (corresponding to the uploaded STL files) are designed for my two extruders. E0 Pulley Diameter: 12.65mm, teeth spaced 7.9mm from the bottom of the pulley. E1 Pulley Diameter: 11.5mm, teeth spaced 7.5mm from the bottom of the pulley. Both extruders utilize a spring with a diameter of 10mm and a length of 9.6mm when fully compressed. Both use 1.75 filament. Though many parameters can be adjusted, it's not guaranteed that any combination of settings will produce a functioning part. However, this is at least a starting point. These mounts are used to attach the extruders to my former BQ Prusa i3 Hephestos printer frame.
