Zetina 6323 sewing machine replacement gear which changes modes.

UPDATE 18.2.2024

After a great cooperation with sewing machine workshop in Slovakia and one of their clients, we made a better version with new measurements (thanks a lot to a great guys from Zvolen!)

  • Printer: Original Prusa mk3s+ (properly calibrated)
  • 0.2 nozzle
  • 100% infill
  • Use NYLON (we tested PETG, ASA and PC blend with no luck, material not strong enough), properly dried
  • Print in enclosure (or temperature stable enviroment) due to a possible material shrinkage
  • clean elephant foot (first layer) from inner diameter of gear

V1 (old version, use rather v2!)

Printed with Prusa i3 MK3s+ with PETG, however, use rather ABS/ASA/PCblend.
I used PETG Devil Design in .gcode, 100% infill.

Measurements are made to fit it as original. Fits and works with knob, however I haven't  managed to reassemble the whole machine yet.

Designed in Fusion 360.
