Gear for Ball Screw Transport - Fischertechnik

Gear Z40 (similar to Fischertechnik 31022) for Ball Screw Transport
Fischertechnik compatible

I started with a copy of Gear Z40 (31022) but this need to long to print (~ 3h)
and it is to expensive too
(Original Sparepart at 1,80 EURO but used Part for example at 50 EURO-Cent)

I made the right one without holes, inner teeth and upside Pins.and
added the shaft part for pressfit mounting on 4mm Fischertechnik Axes.
Sometimes you need to drill a hole with 3,9 mm for better fit.
