Clips on to most electric drum kits, but was designed with Roland in mind. The diameter of the clip for the leg is 37mm which seems to fit a 38.5mm Roland leg quite snugly. The holder will happily hold 7a to 5b drumsticks, and will just about hold 2b, but it's a bit of a stretch.
Make sure you use 3 walls or more to make the clips solid. Arachne walls helps with this too. Infill can be anything, and doesn't need to be particularly high as it never comes under a lot of force. Brims are a good safe bet, but I personally haven't needed them. I printed these in PLA, but I think PETG would be the best bet, as it flexes a bit better and shouldn't get looser over time.
If you would like a design with either a different size leg clip, or stick clips, let me know and I'll have a bash!
This is one of several types of drumstick holders I have made, you can find my others here: https://makerworld.com/@Jammy/collections/1002162
