Over the years I've made Electrical console's for my boats out of Plastic Jugs.
Cut, Weld, install!
No glue needed that I know of.
Who knows more about making things out of cast off Jugs from the Kitchen. Some of those things are almost indestructible.
But most resist bonding by heat. (Welding)
I had the idea of modifying a "Hair Dryer" to make a 450 Degree heat gun just for welding those stubborn polymers. It's just an idea. I'm still alive!
