Bundy Trumpet Valve guide

thingiverse

My son's trumpet third valve seized up on the night of a concert. Further investigation revealed that the guide inside the valve had worn through its brass casing after years of heavy use. Unfortunately, ordering replacements would take at least a week. I designed and printed a new one in about an hour and it took just five minutes to print. I cleaned it up a bit and it fit perfectly into place. This valve now plays better than ever before. I'll be printing two more for the other valves. My goal is to save others from the frustration of a broken trumpet valve guide. The design is specifically tailored for a Selmer Bundy student trumpet, circa 1975.
