Spring Valve Marching Baritone Keychain

thingiverse

So many revisions... but it works! Inside I created a spring to press down the valves on this baritone. It's got .3mm clearance on the sides and 0.5, between vertical surfaces, so it prints in place without any pauses or anything else needed. Once it's done, you should be able to press the valves down with a little force at first.
