This is my take on a way to keep single Heroscape Hex tiles from being tossed into messy heaps in boxes. Currently it is designed to fit into an old RoTV or SoTM box heightwise, but might make some altered heights.

Print 3 of the sliders and insert them sideways into each slot, before twisting them so they snap in place. Might take some moving up and down to get them to go smoothly.

Still a work in progress as I want to alter them to be stackable and to have a clip-on lid to make it easier to pick them up. Let me know what you think!
