Reusable lid for yoghurt cups

#Lid for a yoghurt cup
The yoghurt brand we are buying removed the plastic lid, that was sold with their cups. So I wanted to have a reusable more sturdy lid for those cups

I designed it for these german 500g yoghurt pots, but it might fit other ones as well. As log as the diameter of the yoghurt is ~94mm it should fit. It holds on to the cup with a snap fit.
