Modular Miniature Vise Adapted for Imperial Bolts and Nuts

I loved HD_Creator's vise but I found 6mm bolts and nuts very hard to find in the USA. I revised it slightly to allow the use of common 1/4in-20 hardware which is available everywhere here. I used TinkerCad to enlarge the hex shape in the knob to fit the bolt head and enlarged the slot in the moving block to fit the slightly larger nut. He also uploaded a clamp to attach to the vise to clamp it to a tabletop. I enlarged the slot for the nut in the clamp to use a 1/4-20 nut. His original design requires the vise to be screwed to the table clamp. I used TinkerCad to combine the two parts into one that does not require screws. Here is the link to his table clamp where you can find the rest of the parts: https://www.prusaprinters.org/prints/50360 I want to thank HD_Creator for his excellent work.
