Easel design help

I am designing a LED neon sign with his name for my son. I was hoping to have it be 24 inches tall but I need the track to house the neon strip to be 1/4 in wide. Any ideas on how to do this?

Maybe I don’t understand the question, but it seems like you could just insert shape (rectangle) for the neon strip channel.

Basically I want to replicate this but with his name
