Metric nut & screw measuring tool

thingiverse

I was inspired by many excellent screw measuring tools available to print, such as one created by sneaks on thingiverse.com. This tool measures M2, M2.5, M3, M4, and M5 metric screws up to 50mm long in standard lengths, along with the corresponding nuts. No special hardware or heat-setting is 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 tool was modeled from scratch and prints without supports. I used A2 stainless steel hardware from Bolt Depot. These screws, 8mm long, are available at boltdepot.com. And these hex nuts are also available at boltdepot.com. I'm not sure if other hardware will fit properly or not - the sizes and tolerances of the hex nuts or screw heads might be a little different.
