Modified the scale of @Zykenhouzen_435564 model from printables based on the tip from @jaygraffious_430131 in the comment section.
The model holders are about 25.6mm wide making it very easy to comfortably store your typical ~25mm D&D miniatures or other minis of the same size. The print stacks very well and allows you to store and display 16 of your minis per stack.
Can easily be scaled to fit other size models using the measuring tool in Bambu Studio to check the circumference of the holders.
