My son wanted a secret box based on 3DPRINTINGWORLD's Butterfly Box. I have not uploaded anything but the parts that have changed so you'll need to download files from the original and follow those instructions, but replace the lid and the front panels with these.
This one is printed in TIANSE Violet/Blueviolet and held together with Locktite Superglue.
