A flywheel cage for the Automatic Tommy 20 from BuzzBee.
43mm crush, changeable in the file.

The other cage available on here, was a loose fit (sat on top of the two screwposts and rocked) and the dart entry didn't line up with the darts on the drum were.

This design has caps that sit over the screwposts and is designed to touch the inside of the shell to be much more secure.

As Elite darts are just a mm too long you'll need to cut off the shell face as they touch but the cage has a wall to fill the gap (see the last photo).
You may also be required to trim the guides the orginal cage slotted into, but test before triming.

I've included the OpenSCAD file you so you easily edit it too.

The .STL is for a standard 43mm crush, however if you change the 'Crush' variable (line 24) in the OpenSCAD file you generate the crush you want.
