The Box Becomes a Tool Map
Custom Tool Boxes work best when the interior acts like a map of the set, not just a cavity that happens to hold metal tools. The arrangement should tell a technician what belongs in the pack, where it sits and what is missing after the job.
That changes the design priority. A hammer, ratchet, drill, wrench set or measuring instrument may all fit inside the same rectangular volume, yet they do not behave the same once someone starts removing and returning pieces. Long handles create leverage. Dense heads create concentrated loads. Loose bits migrate into gaps. Chargers, cables and batteries can cross over the main tool if they do not have their own position.
For MRO packaging, the most effective pack is usually the one that makes identification and access faster without asking the outer walls to solve every internal-control problem.
A strong layout can make an empty position obvious, keep the primary tool from burying small accessories and preserve order after the first item has been removed. That is a different job from a one-time shipment carton.
