Box for Stacking Number Blocks

I use Lilac Rage's Stacking Number Blocks in my classroom, but I did not have a proper way to store them. In order to fix this for myself I made a container that fits several sets, including a lid. Several boxes for 1 to 5 sets, each fitting one set of numbers, 1 to 10. Insides are made to fit 110mm x 180mm x 20mm, plus a 2mm margin either direction for easy putting in and taking out.
