I couldn't find a design I was happy with for displaying drumsticks, so I took to learning a bit of CAD.
These should work with most filaments. I printed these in PLA and they work fine, but PLA can "creep" over time making them a looser fit. PETG would work very well.
They should hold most sizes of drumstick. The smaller 7A - 5A holder should also be able to hold up to a 2B, but it's a bit tight, and requires a fair amount of pressure to get it in. The larger size will only hold from a 5B up.
The inner diameters of the holders are 13.5mm for the smaller model, and 14.5mm for the larger one. If in doubt then the 7A - 5A holder is your best bet.
If you find that the grip is too tight or too loose, then you can scale the designs a bit; or if you don't want to print another one then a hairdryer can be used to reshape them slightly, though do be careful as it is obviously hot.
I'll also be releasing a wall mountable holder soon.
If you have any problems let me know and I'll be more than happy to help.
This is one of several types of drumstick holders I have made, you can find my others here: https://makerworld.com/@Jammy/collections/1002162
Enjoy!
