Stackable Ear Saver Stand

I started printing Ear Savers with Hair Bumps (https://www.thingiverse.com/thing:4276597) for the schools my kids attend, and quickly realized they don't stack neatly. Thus, I designed a quick stand to hold them - in sets of 25 - that would also stack.

This is my second iteration, the first version was too thin at the tip and didn't have any cross support on the wedge.

I printed these at 0.2 and 15% infill but it really shouldn't matter for either.
