I often use epoxy to fuse 3D-printed parts. Usually this means that I need a very small batch at a time. Each application uses up a cup and a spatula. Finding suitable mixing cups that do not tip over or are too large has been a problem. Getting hold of suitable spatulas is easier. I often use disposable chopsticks. But that requires cutting the tip to form the small flat point that is needed. Another problem is that I hate cleaning up epoxy spill caused by the spatula falling onto the table. I need somewhere safe to place the spatula after application.

The solution for me has been this design of a small, stackable cup with a small spatula attached. There is an extra area available where the spatula can be placed after use.

I print a batch of these at a time and store them together with the epoxy. This way I always have a cup available when I need one.
