The plastic carrier Craftsman sold these sockets and related tools in is crap.
The case allows the items to fall into a jumble.
I’ve been fixin’ to replace it for years and finally got started.
Still need to build carriers for the wrenches, drivers and a few assorted parts, then make the overall tool box for them all.
It’s mostly Cypress leftovers and 1/4” plywood.
You’ll notice I took the easy route—rectangular boxes with wedges rather than trapezoids.
