I like M&M's...too much. I made this little container to portion one serving size of Peanut M&M's for my daily allotment. You can use it for whatever you need to hold. I tested printing it at 125% scale and it worked great. I'm sure you could size it to whatever you need. 

I'd love to see a Make if anyone prints it really large.

The container is designed to print without support. The lid will need support on the inside. I printed the lid with variable layer height to get a smoother surface on the top curve.
