motorcycle ball mount

My first project with Autodesk Fusion 360

I plan on creating some attachments that go with this for a phone, camera, maybe even cup holder. The opening is 23 mm. You might want to use more infill if you want the part to be stronger. ABS is recommended since PLA might warp under the sun. You'll need some m2 nuts and bolts to attach the 2 parts together.
