Payment processor Stripe has terminated their business relationship with Cody Wilson, an activist who designs 3D printed firearms and milling tools for completing AR-15 lower receivers. His charity Defense Distributed currently has listed for sale in their online store a t-shirt, a sticker, a PVC patch, and a nail suitable for use as a firing pin in a 3d printed firearm. Defense Distributed also sold out its limited pre-order of the tabletop CNC mill named "Ghost Gunner" which is the product for finishing lower receivers, though will also support an open design format so that it may also be used for other aluminum milling purposes.
