Stackable Epoxi Cup with spatula

I often use epoxy to fuse 3D-printed parts. Each application uses up a cup and a spatula. Finding small mixing cups that do not tip over has been a problem. Another problem is that spatulas often fall over and cause epoxy spill on the table. 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 safely be placed after use. I print a batch of these and store them together with the epoxy. This way I always have a cup available when I need one. The object can be printed in any material. I have used PLA or PETG, depending on what I have had loaded at the moment. Printer settings do not matter, since the object only consists of outer walls. The FreeCAD model file is included. Use it for whatever you want.
