This is a Honeycomb Storage Wall holder for the SKIL 4V Pivot Grip Rechargeable Cordless Screwdriver (Amazon).

This will hold the screwdriver in either the straight or pistol grip orientation, and the screwdriver can be charged in place (much easier in the straight orientation).

This uses 3 x M3x12mm screws to mount using 3 x M3 nut inserts which are available from RostaP's original HSW on Printables: https://www.printables.com/model/152592

It was easiest to thread the 2 side M3 screws in from the back side first to cut threads in the plastic before inserting them from the front side where clearance is tighter.
