The flathead and PZ/PH holders are optimized for Wera srewdrivers, but will fit other brands. 

The large holder was printed with a 0,8mm nozzle, to get this out quicker. This was to big for writing this size markings. Unfortunately this came out pretty course. 

The other 2 holders are printed with 0,6mm nozzle, this writing came out very nice.
