Do you have trouble memorizing the dimensions of M2.5 to M10 hardware? Do you want to sink a bolt head or a nut so that it is flush to a part but don't know the height, or diameter of the head? Do you want something that doesn't clutter your desk, but is always standing next to the calipers when you need it?

This ridiculously simple card is for you. It measures approximately 60 x 77 x 5 mm and has enough space for 28 different pieces of metric hardware. These are then divided into two types of bolts, a groove for nuts and a slot for washers.

Tolerances are made for a 0.4mm print nozzle and I like to have the hardware be somewhat snug so nothing falls over, so keep in mind you might need some cleaning or adjusting of the holes.
