Summary

Table Tennis Ball Launcher Project. Fires 6 balls in an arc, designed for a university project.
All printed parts can be printed on a 140 by 140 bed size.
I printed it in abs but PLA would work too.
The gears were bought in and split pinned to the shaft, but these could be printed.

None printed parts, motors, couplings, and everything else needed for assembly can be found here in this document (which has now also been uploaded) : https://goo.gl/SH0vrT
