Gear for Ball Screw Transport - Fischertechnik

thingiverse

Gear Z40 (similar to Fischertechnik 31022) for Ball Screw Transport Fischertechnik compatible I started with a copy of Gear (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 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 a drill a hole with 3,9 mm for better fit. Next step is mixing screw with gear downward so here I´m. I rotate the Original Srew (Horizontal 180 °) to see the Hole at print time. The Gear is only at the bottom for better Printing. (i found out the idea is not new 8-( ) I added the file for the long Screw with 240 mm (but can´t print it) I print one screw with gear and one without Then combine it with long 4mm axes (275 mm long) from http://www.fischerfriendsman.de "Type 6510s #107435 27,5g Achse 275 mm Silberstahl" I calculate how long the axes : Bottom bed 10 mm + Screw with gear 125 mm + Screw only 120 mm + Top Bearing 10 mm + Distance Parts 5 mm = 270 mm long
