Socket set plastic

[Scratch]

My dad has had this small SK socket set for as long as I can remember. As a young child, I remember grabbing this for him many times. After he passed, it is one of the items I am so glad I received. But the plastic that keeps all the tools in place is severely broken apart.

Any suggestions on how I can make a new "organizer" to keep the sockets in their place? I thought of using wood with a router and Forstner bits, but that seems like an awful lot of work.

I have a CNC plasma cutter that can except a router, but I've never used it as a router and don't really want to switch it over and learn how to router with it. If I had a 3-D printer, I would probably use that. Maybe it's time to invest in one…? Do you think they have these online maybe?
