This model was created in Fusion 360. It should print without support, and the two pieces screw together easily.

Dimensions:
Container_Top.stl and Container_Bottom.stl will make a container that is 4.5 cm tall. (shown in images above)

Container_Top_Large.stl and Container_Bottom_Large.stl will make a container that is 6mm tall. (I have not printed this one personally, so if you make one, leave a comment about how it turns out!)

If you would like a container with specific dimensions, just let me know!
