Trumpet Piston Extractor/Pusher - Brasswind Technician’s Tool 🎺

The Story

A good friend and professional brass technician reached out to me because he needed a reliable, simple tool to assist with stuck or stubborn pistons. We know how delicate these instruments are, and sometimes the commercial tools are either overpriced or not quite what you need on the workbench. I designed this straightforward extractor to make his life easier, and now I’m sharing it with the community for free.

The Project

This is a minimalist, functional 3D-printed tool designed to provide a steady, even push/pull on trumpet pistons without damaging the casing or the delicate valve surfaces (when used correctly).
