The Twine Joinery Generator uses a stripped down and light fabric simulation to create a printable and fastner-less joint/connector for any wooden dowels of whatever size you specify. Experiment with it! See what you can make.

Included is the .Blend file as well as a few ready-to-print .STLs to work with 33mm dowels of whatever length you want to use.

Note: Some skill with Blender is required, and a little bit of geometry nodes experience would go a long way in making this tool useful for you. Especially in the early versions. Working on making it more newbie proof in the coming updates!
