Customizable Iris Box

This is an 8-piece (non-preassembled) iris box set-up in 4 easy prints. Customizable and does not require any hardware to put together.
I did include an extra fin in my design file, just in case.
Putting the pieces together can be tricky, but tape really helps.
Full instructions are below.

It makes a fun -and slightly terrifying- candy bowl.
