Reproducing tiny plastic gears for vintage 'gear'

[Jeff_Birt]

Here is a quick 2 minute video of the 3d printed Y-axis (paper feed) gear set in operation. There is still some tweaking to do but it works! In the video I mentioned that the gear fitment was too tight to allow offsetting the two gear halves. It turns out I was trying to rotate the inner gear the wrong direction. The image shows the gears are now offset by 1 tooth.

This resin is quite brittle. I was able to remove a small chip from a tooth with my fingernail. I have an 'abs like' resin while I will try next to see how it compares.
