These Gu dessert pots are delicious, and the glass ramekins they come in are too good to throw away. If you're like me, you've got a unrespectable amount of them in a cupboard somewhere. Have you ever tried stacking them? Nightmare.
Time to solve that.
Remixed from the NOPRO ramekin stacking ring from Thingiverse
It's pretty much the same thing, except scaled down and with a slightly extruded cup to fit the dimensions of a Gu glass ramekin.
67mm insert
74mm cup
