A simple ball joint and insert 3d model that's compatible with Dummy 13. You can use it to create attachable accessories for Dummy 13 or as a joint for something else you're making!

It is recommended to print using PETG or something similar so the joint doesn't crack or snap.

PS. Yes, I know experienced 3d modelers can whip up a similar joint in just a few minutes. This is just a quick and easy copy paste solution for peeps who need it.
