disclaimer: I haven’t done this but… you can use a small screw and washer through the honeycomb panel. It shouldn’t effect the structural integrity as long as you don’t use too many and make them too tight. I’d use beefier clips though:
The cable holders I have are pretty strong and would actually hold, the adhesive on the backing sucks and thats what pops off. Not sure if a strong adhesive would help since the clip is such a small surface area. I thought about using a screw but was worried about structural issues. I guess I will just have to play around with different options and see what works.
My cargo net is a general version meant to have a two sided “basket” net in an suv so I fold it in half & use zip ties & some bungee cords stretched across the bottom in an X shape to give the net the shape and tension I want. It’s my $40 version of a nice gear loft and it works flawlessly for two Hest full size pillows and a dual person sleeping bag.
