A neighbor's son had gotten his mouthpiece stuck in his trumpet late on a Sunday evening and we were unable to remove it. Searching online I noted a variety of simple ‘puller’ options available for purchase and wondered if I could model it and make one - This is the result.
I was never able to test my build as the school music teacher was able to use a similar tool to remove the mouthpiece the following day, but if you build it and find my dimensions need minor adjustments let me know!
Printing
I chose 0.28" layer height and printed with PLA and 30% infill. More would add to strength, given I didn't get a chance to try the part I can't say if this is strong enough or not, I guess it depends on how struck your mouthpiece is!
The top and sliders should be able to be oriented with either long flat side on the bed and printed without support.
The bottom I chose to print with the side without the slider channel on the bed and I used support within the pockets for the nuts and channels for the bolt heads.
Necessary Parts
The build requires 4 plastic parts (1x top, 1x bottom, 2x slider) and a little extra hardware. I chose:
- 3.5" long ¼-20 bolts - qty 2
- 0.75" long ¼-20 machine screws - qty 2*
- ¼-20 nuts - qty 6
- ¼-20 wingnuts - qty 2
*The machine screws shown in my picture holding the sliders in place are 1" long (why they protrude so much). Really a thumbscrew here would be the best option but I didn't have any handy.
Sorry for not using metric hardware here! :)
Assembly
- Press ¼-20 nuts into top and bottom pieces - 2 nuts in each plastic piece.
- Slide bolt head into each side of the bottom piece
- Thread each bolt into the nut pressed into the top piece
- Use extra nut and wingnut together on end of bolt thread to form a sort of thumbscrew
- Place each slider piece on the bottom in the provided channel and tighten bolt/thumbscrew through it to hold it in place.
How to use the tool
- Loosen the slider bolts and open them wide to allow the tool to be mounted on the trumpet mouthpiece area
- Narrow the sliders so they are roughly around the mouthpiece leaving a small space but ensuring they will press against the trumpet sleeve when the piece is pressed with the bolts
- Insert backside of mouthpiece in channel of top
- Use bolts to spread the top and bottom pieces apart slowly and evenly ensuring the bottom piece is carefully engaged on the sleeve while the top is holding the mouthpiece.
