About this 3D model

It's a counter weight (~66g) fixed on a M6 threaded rod. You can choose not to close the bottom with a washer and nut to use it as a foot thing. The M6 washer with a diameter of 19.6 mm fits very nice on top of the M20 nut. The printed part will ensure to fix the counter weight centered on the rod. The washers hide the printed part. The screw is derived from marcaxi.
