I'm working on an Alum one, just have to finish the other mods first.I took everything off yesterday and have started work with a friend on a new solution to give it a diaper change. Decided on a 3 piece design to keep cost down and not have to glue and weld and sand the 3d prints, because I dont have a 15" bed. Needing to squeeze it in on my bambu x1c. Pic for attention. My initial design will retain use of the half cover. I wanted something I could pull off real quick if I needed to grab a trailer in a hurry.
