The Original 3d Printed Trombone!

This is a comprehensive guide for building a 3D printed tenor trombone from various parts. Here's a step-by-step breakdown of the instructions: **Preparation** * Print the inner slide, outer slide, and lower round using a soldering iron to attach the m3 cap screw and rubber washer. * Test fit the entire assembly together with the inner and outer slide. * Cut a 1-inch long section of schedule 40 ½” PVC pipe (21.5mm OD x 15mm ID) and install it in the back of the inner slide mounting block. **Bell** * Print the bell with a brim, ensuring a dialed-in printer and using high-quality filament. * Allow the bed to cool completely before attempting to remove it. * Trim the edge brim and set aside. * Print the upper cone and extension pieces on their integrated print raft. * Use a plastic model razer saw or a flush cut saw to cut the parts away from their rafts as close to the raft as possible. **Tuning Slide and Main Frame** * Print the upper tuning slide round, the lower tuning slide inner slide mount block, and the bell support brace. * Cut two 101mm long pieces of Sdr9 PEX 5106 tubing and install them in the cups in the upper tuning slide round until they bottom out. * Cut two identical 95mm long pieces of flowguard gold material and install them into the tuning slide inner slide mount. **Assembly** * Wrap plastic packing tape or electrical tape around the ends of the inner tuning slide to limit its movement. * Pull the tuning slide out to lower the pitch of the trombone, and push it in to raise it. * Cut a 16” long piece of ½” schedule 40 PVC pipe and fit it into one side of the tuning slide inner mount. * Fit the bell support brace over the end of this piece of pipe, then install the other half of the slide disconnect union fitting onto the end of this tube. **Mouthpiece** * Print the mouthpiece with the mouth portion split from the shaft. * Cut both pieces away from the build raft with a razor saw or flush cut saw, then glue the shaft of the mouthpiece into the upper cup of the mouthpiece. **Adjustment** * Depending on the fit of your slide, you may need to add width to the inner slide to minimize air leak. * Apply trombone slide oil (or other food and plastic safe oil) to the slide surface. * To start making music, pull the tuning slide out approximately 50mm. Play a note in first position, If the trombone sounds flat, push the tuning slide in. if it sounds sharp, pull more slide out.
