First decide the gear ratio you desire. 16/56 = 3.5 is most common:

Note: 48 and 32 wheel available on request. You will need to order a shorter belt as indicated.

    • There are many options for filament between type and color. You can mix and match to suit your style and needs.

    • Generally I recommend PETG as it has good all around properties. This is the same as the stock extruder. I used an all PLA version for about 9 months with little trouble however. Annealing is another option, but is challenging due to the shrink factor.

    • Certain parts have unique needs that will favor one type over the other. See part listings.

    • Some parts make look slightly different over time as new versions come out, but functionality and printing are correct as listed.

    • I use and test all parts in Slic3r PE. Print parts as oriented, do not rotate around X or Y. Using default settings unless otherwise indicated below.

    • recommend 0.15 layer, gyroid

    • Tail - similar to Prusa style connection

    • Fin - more flexible, less resistant connection

    • Note that the wire rack at the end of Fin is designed to have split openings at the top even though the stl appears closed. This will resolve when you slice.

  6. This part is separate and small so that you can print in a high temp resistant filament. Has two small breakaway supports that should be removed.

    • Std version: this is similar to the stock Prusa extruder, where the PTFE is cut flat and terminates before the gears

    • PTFE version: this has the PTFE pass through and needs to be cut tapered to fit between the gears. This is best suited for flexible filaments.

    • Optionally print at 0.1 layer with 0.25 nozzle for extra high precision for tightest fit with Bondtech drive gears. No escape for flexible filament!

    • It is best to print this part by itself and not plate it with other parts. This helps ensure you get clean teeth.

    • Print either the 56 or 54 tooth version depending on the gear ratio you want.
