Dụng cụ đo đai ốc và vít hệ mét

I was inspired by a lot of great screw measuring tools available to print, such as this one by Sneaks. This tool measures M2, M2.5, M3, M4, and M5 metric screws up to 50mm long in standard lengths, as well as the corresponding nuts.

No special hardware or heat-setting required, simply add the hex nuts and screws to the base, then use a little super glue to attach the top to the base.

This was modeled from scratch and prints without supports.

I used A2 stainless steel hardware from Bolt Depot.
These screws, 8mm long
And these hex nuts

I don't know if other hardware will fit properly or not - if the sizes and tolerances of the hex nuts or screw heads are a little different.
