I was frustrated by the options available online...you either get a road worthy tank sized case for $$$$$ or a flimsy flatpack stand (also $$$ considering what you get for you pay).
This one can be customized with extra padding and extra supports on the cheap.
I'm using the plans found here (adjusted for 2 extra guitars, I can give you the changes you need to make if you want to do the bigger one)

This one is pretty good just because he gives you a few closeups at different angles if you need help visualizing. Note this one lacks the middle bar.

Just wondering if anyone here has done of these before? Maybe you want to start one now

Go ahead, I'll wait here while you run off to the hardware store
