Dump style bomb drop

This is a bomb drop designed to load up with all the stuff you can't drop via conventional bomb drops. I plan on using this with pop rocks or other things and in hopes it will work. This may not work as I am using tinker cad but I'm doing my best. I would love someone to give me feedback on it if they can.

There are 2 lids to choose from depending on what you prefer. I have a pushing lid that the servo pushes the lid shut. And I have a puller lid, where the servo pulls with a rubber band and thats how it shuts. either way they both should work. (not positive). You will need some glue for this design.
