Right Angle Helical Gears

These gears are angled at 45 degrees such that they can mesh at a 90 degree angle, on two perpendicular 3/8" shafts.
One has a standard keyway, the 'keyed' one I added the key into the STL.
I intended this originally for testing out ideas for a power transmission on a printer design, but benched the idea for a later date.
