I started out making a finger splint, then tried to make it fancy and created a box with random in fills. If you use the size as is, it can double as a splint for a finger--use at your own discretion for that.Here are what the parameters mean: box_l, box_w, box_h = dimensions of the box use_frame = true if you want a solid box frame use_frame = false if you do not want a solid box frame density = number of supports per side. Keep small to avoid crashes wall = diameter of support members seed = random seed value--try any number!
