I have tested it on the YTS-62III and YTS-23 and it should work on all other Yamaha tenors. The diameter of the neck is 27mm so if a different brand is the same size it should work for that. It fits well in the original cases that came with the YTS-62III and YTS-23 with the part that sticks out being 18mm. I have included fusion 360 files so this can be modified to your needs.
