Inserts for Army Painter Bottles

I had trouble getting all of my Army Painter mini paints organized and stored away when not in use. So I designed an insert for pretty much any kind of tool case. I bought a aluminum tool box at my local hardware store and glued the paint holders in to the lid.
It works like a charm, and they stay in the lid even when slamming it shut.
The holders are designed to accept Army Painter dropper bottles, but can easily be resized for other brands. Note that it allows the bottles to be stored both right side up and upside down.
It is designed to be printed with minimal support. Only the retainer tab at the bottom of the model needs any support. See picture of my placement of the support enforcers. The rest will print just fine.
You should use PETG for this print, as PLA tends to loose its shape and springyness over time.
