Gridfinity Module for Wiha Picofinish Screwdriver Sets Fits 2 "smaller" and 4 "larger" ones per Tray. Fully Stackable, 3x4 and only 3 Units High.

Compatibility: I am using this for my Phillips/Slotted (42990) and Torx (42996). The Allen Key Set (42993) will unfortionately NOT fit completely because the Biggest driver is too long for the Tray.

Printing Really Simple: No supports, mine are printed with a 0.6mm Nozzle, 0.4mm should be absolutely no problem.
