Should be easily printable on pretty much any printer. It is designed to be very thin walled (only two layer). This way it prints quite fast but is astonishingly sturdy due to the construction. It fits standard Wiha PicoFinish screwdrivers. For other screwdrivers there are a couple of sleeves which can simply be put into the original (conical) holes. Due to the layerlines they 'snap in' and stay in place. The photo shows my screwdriver zoo.
I printed mine in 0.3mm layer height and PLA. Works like a charm. Print upside down with legs pointing up (as shown in the preview)
