Cylindrical twist lock coupling

These are two small cylinders made to insert and twist to connect together. These are meant to be edited into larger models to connect parts easily.

At the current size, sliding parts have a tolerance gap of 0.25mm.
This tolerance also overcomes any need for filing or difficulty fitting the parts into each other due to first layer squish on my printer.

Printed fine with no supports on low quality.
