Overview
A tool roll built from a repurposed camera filter pouch. The original pouch had mesh pockets that couldn’t hold small tools securely, so I removed four of them, sewed waistband elastic down the interior spine to retain drivers and hex keys, and added two Tyvek flaps cut from a USPS mailer to keep everything contained when the roll is closed and bouncing around in a bag.
It’s a small project, but I use it nearly every day. Every tool in it has been picked because it solves a problem I’ve actually run into. 3d printer fixes, slide rule assembly, climbing hold tightening, pulling out nails from the walls in my role as asistant art curator, epoxying together the cracked base of my camera. It carries enough to handle most field problems without turning into a full toolbox.
The whole thing, pouch plus caliper case, fits in one bottle pocket of my backpack, right next to my slide rule.

Field Iteration
In ProgressAdded scissors and a carpenter pencil after initial use. Coordinating the pouch with a separate car kit (impact driver, sockets, consumables) so the full system covers on-the-go repairs without duplicating weight.
