Balanced Trumpet for One-handed Play

Accessible Trumpet Holder

Ran into a situation where I needed one of these on short notice for my mini-me after he broke his left arm right before a concert, but the commercial versions were stupid expensive and couldn't get here in time anyway.  So I threw together a 3d model and printed out the parts I couldn't get from amazon and built my own version.  Ended up costing about 1/3rd what the commercial models cost, and all the store bought parts can be re-purposed for their intended purpose later.

I put the models up here if anyone else needs one: [https://www.printables.com/model/460176-accessible-trumpet-holder].  I recommend printing everything except the top brace structural piece from TPU.  Print that one structural piece from PETG or something similar.  The picture of mini-me playing using it is using the V1 models where I used tennis balls for the top pad - the V2 models with the TPU pad is much nicer and should be easier on the trumpet's finish long term.
