I bought the Justech Precision Screwdriver set off Amazon. Although a great entry level kit, the blow moulded screwdriver case left something to be desired. The guides to position the screwdriver itself could be better, as it can take a little jostling to get it to close just right.I also needed to shorten the holding strap with some quick sewing, as this case is considerably smaller than the original one.

I've like to add a proper closing mechanism to the front, and perhaps build in some more space for other things. But it serves me well for now, and works pretty well for a prototype.
