Simple fix for ABP gear slip

I hope this simple fix helps someone else in the same predicament I was.

I ruined the snap fit slot on my MakerBot Automated Build Platform while I was learning to use the ABP. (Tranlated to English: I had to replace the belt several times due to my screw-ups.)

The wooden snap fit slot holding the geared roller loosened to point where the motor gear would force the roller gear out of the slot and slip.

This simple paper clip fix has held up through 14 prints so far.
