iPhone 6 trombone bell amplifier - Bach 42/50, customizable

prusaprinters

<p>Want to let others hear a song after rehearsal and can't because that tiny phone speaker just isn't loud enough? Put this little part in your trombone case. Then surprise everyone by connecting your iPhone 6 to your trombone bell and it will be really loud!</p> <p>Picture shows it attached to a Bach 42B and a PrintBone bell. It fits a regular brass Bach 42 or Bach 50 bell, or any trombone with the same connector (Yamaha 622, probably some Edwards models and more), including the PrintBone.</p> <p>Have another kind of phone or trombone bell? Press the customizer button and easily adapt it to your own equipment.</p> <p>Of course, a trombone bell is not made for a linear frequency response, so it will sound a bit like those early gramophone-players with a horn.</p> <p>If you want it with a PrintBone bell: <a href="https://www.thingiverse.com/thing:1845509">http://www.thingiverse.com/thing:1845509</a></p> <p>I printed it on the fastest setting available to my printer, without support or brim. Use whatever infill you like, 10-20% should be fine. Perimeters might have an effect on airtightness which will have an effect on acoustics, but with 2 perimeters it worked well. Might even be better with slight leaks.</p> <h3> Print Settings</h3> <p><strong>Printer:</strong></p> <p>Original Prusa i3 MK2</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div><strong>Supports:</strong></p> <p>No</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.35mm works</p></div><strong>Infill:</strong></p> <p>Whatever you like, mine is 20%</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>Printed at the slic3r fast preset from the original prusa i3 mk2 drivers package, which seems to prints at the E3D v6 extrusion limit - have to limit the part cooling fan to be able to print at that speed :)</p></div></p> </p></p> Category: Music
