I printed my canister at 35% scale and the cap at 35,15-35,3% scale so it isn't too hard to put on and tighten. Printed out of grey PET-G and cap from PLA but PET-G would be better to handle chemicals. I WOULDN'T RECOMMEND putting drinks and bewerages into this bottle. It can be used for engine oil, cleaning liquids, shower gels etc. Check if it's watertight before putting anything from that inside. The model doesn't require any supports inside of it but only a few to support the 3 handles. Enjoy :)
