Tri C0rner Traps - DYI ??

Have any of you made dyi versions of tri corner traps that look triangler and are put at the ceiling - wall corners? If you have , can you outline what you used to build them and give a detailed description as well as how they are attached to the walls.

Not sure if this is what you're looking for, but do a search here on A-gon for "superchunks". I built a pair of these for peanuts & they work well...certainly as good or better than anything you can buy. Depending on your woodworking skills, you can finish them to look like fine furniture if you wish.
