I did it for my daughter (also the crazy colors). It has room for up to 64 stud earrings. The holders can lie in the shell and they are protected from falling out by the green covers. The subjects are so big that my daughter can reach in well. For me it would be too small with my stubby fingers :-(. I've made a second version with bigger holes. the holes have a hopper and are a little bit bigger at the top, so the earings could be placed easy and have a hold if the stick insight. One has 2 areas with radius 0.7-0.5 mm (lower) and 0.6-0.4 mm (upper). The other has 2 with radius 0.9-0.7 mm (lower) and 0.8-0.6 mm (upper).
