Ping Pong Ball Dispenser

thingiverse

This is an Automatic Ping Pong Ball Feeder that operates by sliding the "distributor key" into a narrow rectangular slot on the "delivery tube." A small rectangular opening should align with the peg on the "distributor key." You connect "delivery tube 2" to "delivery tube" by lining up the angled portion at the top of both prints and using the guide bars found on "delivery tube 2." Simply insert five ping pong balls into the rear of "delivery tube 2," then press the key down into the ground, lifting the entire device back up. When tilted, a ping pong ball will fall out. This design was created for the Northrup Grumman 2019 Design Challenge. In our case, the Feeder was mounted on an unmanned aerial vehicle (UAV), hence the angled portion at the top of the prints. Thanks for viewing my design; please leave a comment if you have any questions.
