This gear bearing is a remake from http://www.thingiverse.com/thing:53451
I add flange on Top and / or Bottom of the gear. It can be customized on scad file.
The stl has
- 10 mm height,
- 40mm outer diameter,
- 42mm flange diameter
- 1,5 mm flange on top and bottom.
You can change the dimension using included scad file.
