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".
If you want, you can buy a mini trombone stand separately from my shapeways shop, "Michael's Awesome Shapeways Shop". This would allow you to print each model in a different color/material.
Speaking of materials, I have only test printed this model with "Strong & Flexible" material, so I cannot guarantee if it is possible to successfully print them in any other material, due to the model's 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.
