20oz 18mm with straw diffuser

Remix of bottle cap bong by wbarber69 which uses a 18mm bowl instead. Original file included a stem but the connecting section broke off in several prints so to save time I made use of a McDonald straw as a stem with the included diffuser on the submerged end. Small hole on the tube of the diffuser included as a place to add hot glue if necessary.

Like the original, can be used with all standard bottle sizes and mouth piece perfectly seats lighter between uses. Please check possible toxicity of plastics you choose to print with and wash parts before use.

Some air leaks can occur near the thread but fixed easily with packing tape, thicker bottle recommended for solid grip while threading. Overall impressive performance, BE SURE TO THANK THE ORIGINAL DESIGNER.
