The ILS Robotics team 520 gave out 800 Peg Pullers at the 2018 VEX IQ World Championship. If you did not get one or would like more here is a link to the CAD I posted at Thingiverse so you can print your own.
If you don’t have a printer or don’t want to mess with it you can purchase some at ilsrobotics.com or ebay.
