I have this BonnaCase for my bass trombone: https://mbcases.com/portfolio/cases/trombones/case-for-detachable-bell-bass-trombone
But the accessory compartment only contains a cumbersome mouthpiece pouch. All other accessories have to be tucked away next to it somehow.
So I made myself an organizer that keeps all my accessories neatly organized and always within easy reach. It contains slots for two mouthpieces, slide cream, water spray, valve oil (Curtois), and tuning slide oil (JM).
Printed in PolyTerra. The matte finish fits perfectly.
The case finally feels like what I expected from the manufacturer. I should have done this much sooner!
If you are interested in the OpenSCAD file. drop me a note.
