Small Hardware Organizer with built in Metric measurer.

thingiverse

Here's a metric hardware box I designed that works for other sizes of hardware (M2-M5) and combines the Socket Head Cap Screw, Long SHCS, and Countersunk Screw Amazon/ebay kits into one box. It also includes a spot for the nuts and washers. If you have those kits, the boxes take up a lot of space and the dividers let the hardware mix anyway. The screws can be tight in the box, so tweezers or needle nose pliers sometimes come in handy, but I usually have them on my bench already. There's no latch, because I use a little carrier that slides into it to keep it shut. The tape has been working well for me over the past few months. The lid has built-in screw measuring for both cap head and countersink screws. The lid is held on with M3x20 screws as hinge pins. The countersunk screw measuring isn't perfect, but it works well enough to get you organized. This was supposed to be part of a whole modular system/customizable system, but I lost interest in it. Included are a "blank" lid and a "blank" box. I figured I'd share it anyway!
