Paintball bunker cap

Summary A friend of mine give me a dozen sup-air ball bunkers as a gift, but they didn't have there air caps, so I made my own design and printed them and they work perfectly, This are for 24mm diameter threads I printed mine with PEGT because it is what I had but I guess that PLA and ABS will works as well Print Settings Printer Brand: Printrbot Printer: Play Rafts: No Supports: No Resolution: 0.1 Infill: 15% Filament: amazon PETG white
