Gas Bottle Cap

Id recomend printing this out of a harder TPU. I uploaded the step file if you want to change sizes but scaling in the slicer will work as well. The piece that fits inside the fitting is 15 mm, so if your fitting is a diffrent size inside you can use this equation. (your needed size + 0.5 mm for a snug fit) ÷ 15 x 100 = the percentage you need to input in your slicer's scaler. Happy Printing!!
