Actually I thought about it, making a small profit from it, but it's WAY WAY WAY too much work... I'm talking about the most work I had to do for a DIY project... source the wood, order, collect, sand, measure, cut, saw, chisel, file, sand, drill, glue, stick, etc etc etc etc.... took me 12hrs just to make the structure alone..
Only now do I understand why they charge $180 for making one..
