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
