I want to build an octagonal box, whose sides would be cut from something like laser-cut 1/8-inch lexan sheet. But I'd really like the corners of the box to be as smooth and seamless as possible, and I'm a bit stumped as to how to accomplish that. Any suggestions?
I'm pretty sure the laser cutting machine can't miter the edges.
I've considered building the corners by gluing the side pieces (on the inside) to angle brackets, then covering the seam with some sort of tape. But that sounds like it will be hard to make it look good. I'd also be willing to consider something like a notched plastic dowel at each corner, where the sides fit snugly into the notch. But I haven't been able to find such a notched dowel, and can't think of a way to reliably make one.
Any other ideas? Any brainstorming will be appreciated!
Thanks,
- Joe
