Spade bit holder

I needed a modular tool holder to clean up my shop. This is is designed to hold 13 spade bits with a shaft of <5/16" diameter
There is a tab on the left side of this, and a slot on the right side that an adjacent modular rack slides into. I will be posting one or two of these a day as I finish cleaning my shop. I have finished a Bondus Torx driver holder, am currently printing a Klein nut driver holder, as well as Bondhus standard and metric Allen key drivers.
