3" inch purge plug
Description
3" purge plug for my fellow tig welders out there. this thing is designed to be used with about 2.85" and larger tubing with a 3" maximum. shes a nice tight fit so be sure your printer is up to snuff. - for a nice flexible one, print with 10% infill - for a purge plug useful only as a hockey puck: print with 80%+ infill - this should be obvious but this is only useful if printed with TPU!!!
