M5 Nut and Bolt (Scaled 5x)

thingiverse

This was originally something I wanted to do for my 3 y/o son for motor-skill development. The models were taken from McMaster but I had to modify the fitment so that it wouldn't be so tight. Normally the threads on the bolt/screw have a 5mm major diameter but I've changed it to 4.91mm so that it has approx a 0.4mm gap between nut/bolt threads (see Solidworks measurement). I've included the solidworks file if you want to make mods.
