3" inch purge plug

3" inch purge plug

thingiverse

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!!!
