Blowpipe Threaded Stock

A threaded stock for a bellows blowpipe. Simply cut a hole in your pipe bag the width of the threaded section, and from inside screw the internal locker onto the stock. Then, the valve assembly screws onto the stock, and an alignment ring helps glue on the hose connection straight. This is printed separately to avoid having to print a tall, skinny and top-heavy part.

Usually this design would include a pair of O-rings, but in this case I just smeared some liquid gasket maker on the top of each part, allowed it to cure, and then assembled. You will need a small circle of rubber, silicone, or leather for the flexible portion of the center valve.
