Experimental! the Toranado plastic gear

There is a 2 gears, 10 teeth and 50. Orginal gear ratio is 4.97, remix 5.0.
Works well, printed and tested. Please, if you will instal it, write to comments works it or not. The hole has less than 5mm diameter after printing, so you will need to adjust the aperture under the pulley manually by mechanical or chemical way for tight fit on a shaft.
