I was asked to design a Christmas ornament candy dish. This is what I came up with. This was printed with a .8mm nozzle at .4mm layer height. 15% Infill seems to be work well. I have one printed with 0 infill and the top is very weak. The crown isn't the best design but with my extremely limited design knowledge I think it came out pretty well.
For the holes to put the clip in, I used a soldering iron to melt the main dish. You can use a drill as well. Put the crown on the lid and mark the 2 holes with a sharpy. Then either drill them or melt them.
EDIT: I have added a hole to the crown part of the dish. I have tested this so you can put the crown on and just put the clip in and it will be held. I have left the older version in for those who want to make their own holes.
