Sandblaster_Coke_Bottle

Print the handle upside down.
The rubber gasket should be printed in some kind of flex material. I used PrimaSelect Flex or something like that, but use whatever flex you have lying around.
This was printed and tested using 3DE Premium PETG.
I'm still testing the durability of it (using the thing regularly) and so far no issues (except for that one time I used wet sand and clogged the nozzle. Don't use wet sand :P)
