Wall mounted 1/4" screwdriver bit holder.
Footprint approx 200mm x 85mm.
It was designed for the space I had available and not designed to fit as many bits as possible into given space.
For the people who are all thumbs, it should be easier to extract the required bit.
For the eagle eyed, the bottom fixing plate didn't print on this first one, it has now been fixed.
