Inspired by Toolbox Widget type organizers and based on a similar design by kickit2 on Thingiverse. Fits 12x5mm round magnets in the base (2 pcs 12x2 works as well). There is a single and double of the full size and I added a double in a smaller size for more compact storage of smaller wrenches. I'm using these for wrenches up to 1-½" or so and down to ¼".
Update: the tapered style works great for screwdrivers too. I added a new style with a parallel section that works well for pliers and socket extensions etc.
Update 2: by request added 3 different size spacers for larger screwdrivers etc.
Update 3: Mk2 designs added! I updated the magnet pocket for easier printing and gluing, and added a bunch of new designs and spacers. The wrench holders now have a slot for a size label, common sizes are included as well as a blank one.
