This design is a wall mounted screwdriver holder for between 4 and 30 precision screwdrivers. Use the Customizer to fine tune parameters and create STL files that fit your particular sets of precision screwdrivers.
The holder is made so that it is possible to print several with different tube diameters for different size screwdrivers and still mount them side by side.
As an alternative you can print my customizable free standing screwdriver holder. In that holder the screwdrivers are placed upside down and the holder is placed on the desktop. You find that design here:
