I printed mine in PLA for the main canister and the latch anchors, but you could print them out of any material. The latch is flex with a 92 hardness rating. The gasket is Ninjaflex. The canister was printed with a layer height of .30 and used between 1/3 and a half a kilo of filament. Took about 18 hours on my Prusa i3MK2S for the canister. Depending on settings your mileage may vary.
