The author remixed this model.
Inspired by AaronOaks design but it didn't fit my larger bits. I needed slightly larger/deeper slots for my larger bits. Holds 12 bits ranging from ¼" to 1 ¼". I added side cut outs to make the bits easier to grab. First attempt at designing for Gridfinity.
Used the Fusion360 Gridfinity plug in by Lev Mishin: https://apps.autodesk.com/FUSION/en/Detail/Index?id=7197558650811789&appLang=en&os=Mac
