G/Flex Epoxy Holder Gridfinity

This is a Gridfinity bin I made for holding these G/Flex epoxy containers. It will hold them both right side up and upside down, if the base is open like in the picture. It also holds these cups I found in Amazon that I mix the epoxy in and also holds some popsicle sticks. Very cool when I need to glue on a knife handle. I just take the whole ting down and it has all I need.
