Printed it in 2 pieces with the flat side down so it would be a clean print.

The notches the shells slide into are a little undersized and need some additional trimming in order to get a good fit.

You will need:

A 608 bearing

m2 8 allen machine screws
m2 12 allen machine screws
m4 8 allen machine screws

Cut down spent 45 shells to 13mm

I used this finger cap:

The 45 shells are left overs from some I cut down (using a copper pipe cutter) for nut covers on my motorcycle. I had a really hard time cutting down 9mm (a dainty round), so it would have to be modified to fit a full length round. Result, don't expect to see a 9mm version any time soon, because it could end up making it too long to work. Plus I don't have access to spent rounds for the next few months.

Now this is a spinner. It's got plenty of detail and it involves one of my favorite things!!!! Great job! and I second the 9mm version please!

can you make a 9mm version?
