Small 90 degree gearbox

Small 90 degree gearbox

grabcad

A fairly simple 2 stage gearbox. Use Aluminum rod for the shafts, a couple of small ball bearings and 3D print the rest to have a functional but somewhat noisy (the teeth are just triangles) gearbox. This was first modeled back in SolidWorks 98. The fanciest bit is the top and bottom covers which were modeled as one piece and split with a knitted surface to include the lip. I don't have a set of drawings anymore to include here. I did include a STEP file for non SolidWorks imports.
