Umbrella bowl. 

You will also need a 3mm skewer for the shaft. I found these skewers vary in size so the fit might not be quite snug.

I mainly made these to hold the crystals from the board game Unicorn Glitterluck so my kids didn't lose them while we were playing. You can do one in each colour for each unicorn. For Unicorn Glitterluck I used a little bluetac at the bottom of each plastic piece. It holds everything in really well if the skewer is loose but is still removable so you can take the handle off to be able to pack it into the box when not in use.
