HPA bottle holder adjustable version

Hybrid PLA and TPU HPA bottle holder designed for 48cl 3000PSI bottles. Attaches to molle vests and is secured via cable ties. The HPA bottle can be secured in the holder by using elastic, I used hair bands with short metal bars on the ends for easy swapping. You MUST use a soft TPU filament for the grips otherwise they will be slippery and not hold the bottle securely. The TPU sections friction-fit into the PLA parts and don't need gluing. The bolts used are 2 x M4x30mm cap heads and 2 x M4 nyloc nuts
