I got tired of seeing my plastic totes fall apart every few years and go to the dump. When I found a bunch of discounted aluminum channel, I knew it was time to build a better box.
In fact, I built six of them. I cut them out of 1/4″ birch plywood with a Mars 130 laser cutter and finished them off with hardware from diyroadcases.com. Design was a cinch with custom files created on makercase.com. I used the finger joints design option for extra strength. The box was glued together, trimmed with riveted ball-corners, and finished with multiple coats of black spray paint and acrylic caulk.
Is it a better box? Time will tell, but all signs point to yes.
