I did this part to fit inside the grenade launcher barrel of my Star Wars CA-87 alike blaster. It holds a LED ring and a small speaker, so the blaster has lights and sounds.

The second part is a cover for the LED board so you can conceal it or add more greebles on top (I added some hollow rods and a mesh).

Edit 1: Added the custom supports for the scope. I used, as base for miy blaster's scope, the DL-44's scope, so they should fit one of those if you want to use them.

You'll need to do some holes for screws or use hot glue to attach the parts.

If you use the scope's supports, you can attach them with real screws for added realism.

I just used Fusion 360. This is my first model with tat program.
