Plastic nut and bolt for Battat take-apart toy

thingiverse

Plastic nut and bolt for Battat-style take-apart toys. The bolt features a hex head with a crosshead screwdriver slot, as well as lengthwise and widthwise anti-choking holes to match the originals. Minor adjustments to dimensions may be necessary depending on your printer's capabilities. The hex bolt head and nut bodies are not tapered like the authentic versions but do have chamfered corners. Thread dimensions approximate 9.5mm minor diameter and 12.5mm major diameter, with an approximately 4mm pitch. With careful stretching, these components could probably fit other take-apart toys. The nut has only one turn of thread inside, making it more forgiving of mismatched pitches. However, the nut model could be improved as the ends of the thread taper to a weak, delicate edge.
