Now I am starting to colonize my second 20-unit rack box, I worry it might fall flat from the weight of the modules I plan to eventually fill it with. Well, this is almost guaranteed because I already wear it with a guitar strap.
I noticed the extra, undocumented M3 screw holes in the ends of the case units and decided to add some stay-wires to keep things at the right angle.
I found a picture mounting kit at my local hardware store. I cut the wire to fit neatly with a comfortable angle for the second case attached via the hinge kit. I used red heatshrink to cover the rough ends and reinforce the join.
I was originally thinking to use metallic fishing line, the kind you would use fishing for barracuda or other similarly bitey fish. I think they can come in black and red etc. but I didn't have a fishing supply store nearby.
I may heatshrink the whole wire later for looks and insulation. They could make handy Theremin antennae too!
