Crossbow Roller Nut

I got a crossbow kit from Alchem Inc. when I was about ten. I never finished a crossbow, but I hung onto the parts for... 14 years now. I finally sold them for peanuts to an excited SCA member.

As a token to my fifth-grade self who didn't have the tools or knowledge to make a decent roller nut, I made a blank to send with the rest of the kit:

I didn't have any metal adhesive, so the steel parts are just a tight interference fit with the aluminum body. I hope the recipient puts it to good use :)
