I keep an entire electronics toolbench in one of those two layer travel cable organizers. I've got a Pinecil, flat metal folding stand, a 3D printed wire holder, a magnifying stand with three long Doc-Ock style helping hands, a box of six different color 22AWG wire, calipers, solder, a flux pen, three kinds of gripping tweezers, and an incredibly useful simple non-mechanical 3D printed round vise with different wedge-shaped parts to mix and match to hold stuff, a silicone workmat with molded screw trays, wire cutters, and a small flat cutting mat with a grid and ruler on it. I throw it in my backpack with a big ass Anker power brick that can power the Pinecil easily and a project box of whatever I'm currently dicking around with and go to my local cafe and do all my soldering at an outside table like a big ol nerd. It's all verrrrry tightly put in the case but it's still easy to carry, if not light.

(I have another identical one for all of my little Pi cyberdecks I like to build, the small touchscreen I use with them on the go, and various cables and adapters.)

But I just ordered one of these bags to put my actual tools in - screwdriver set, another wirecutter, the tiny adjustable wrench I got from Temu, my multitool, etc.

I have an entire low rent electronics/fabrication/3D printing/woodworking workshop mostly of Marketplace finds, but I dig being able to just throw this stuff in my old Boblbee backpack and go sit in the park and do nerd stuff. :D <3
