A very handy tool for holding parts while the paint dries. Simply attach a rod of 1/8" (3mm) or smaller to the bottom of your models and place them in this holder while you are painting them. I drill holes in the bottom of my pieces and then simply insert a 1/8" or 1/16" diameter piece of brass into the bottom of the pieces, it's a great way to hold the parts when painting and then I place them in the holding jig while the paint dries. You can also attach your minitures/figures to the tops of large nails, this is a much lower cost solution than brass rod, just make sure the nails you select are 1/8" (3mm) diameter or smaller.
Photos show the "Version 1" with 1" spaced holes. Version 2 is identical except the holes are spaced at .6" (15mm). Version 3 is exactly like version 1 except the holes are large, .160" (4mm).
