Giá đỡ chai nhỏ (dầu súng)

I built this little holders to carry oil to the gun range. It fits the little gun oil bottles I have. By printing the 2 or 3 and putting it in a pocket, it helps the bottles stay upright and also prevents them from being pressed.

They might also help contain a spill, although I put the whole thing in a ziplog-like bag.

I recommend printing with organic supports like in the photos.
