Make the adapter any size you need it. Straight attachments, Tapered attachments ... heck I think you could even print it to be an entire downstem attachment for a billy if you're that way inclined.

My first time using OpenSCAD for modelling.

Updated 19/07/2015: added "Easy Valve Adapter Diameter" to help compensate for shrinkage in different materials.

Updated 16/04/15 : added ability to customise "the button" also tried to harden the input values so you can't break the design so easily.
