A replacement straw for “Great Stuff” spray foam canisters. If you're like me, you have many small jobs, but after one use, the straw becomes clogged and unusable. With this model you can print your own and reuse a partially spent can again.

The model comes in 100mm & 150mm lengths, as well as a 45 degree angled version. Print one lever and then a straw each time you need to reuse. I find it also helpful to place a plug such as a drywall screw (1.25") into the canister immediately after use to let you remove the last 30mm of foam that is inside the tip upon next use.

The internal thread will directly mate with a Great Stuff cannister, and the lever can be reused repeatedly, just print a new straw each time and screw together.

This model works well with variable height slicing since the threads need some detail but the straw does not. I included a variably sliced model for the 100mm tip and lever.
