This is a very accurate and detailed miniature trombone which measures about 10.5 inches long. It was modeled by an actual musician, me, and is based on a real trombone, a Buescher Aristocrat to be exact. It has been designed to be in scaled with "Michael's Mini Trumpet".
It comes with its own miniature trombone stand so that you can display your mini trombone on your desk or on a shelf, but you can buy the trombone and the stand separately from my shapeways shop, "Michael's Awesome Shapeways Shop". This would allow you to print each one in a different color/material.
Speaking of materials, I have only test printed these models with "Strong & Flexible" material, so I cannot guarantee if it is possible to successfully print them in any other material, due to the models' small details. In fact, the spit valve in my test model broke during production. However, I have seen a picture of someone else's print of this trombone and the spit valve is just fine.
If you have any questions, feel free to message me or comment bellow.
