I made this simple driver & bit holder for my workshop bench.  It holds 4 Ryobi electric drivers plus hex bits.  I incorporated the hex bit holder from RedNightPrinting, which is ideal for holding a 13-bit hex drill bit set from Harbor Freight.   There is room for a number of driver bits on top between the drills.  I made this so that the 4 drills stand upright while allowing them to charge.  (I use the bit slots on top to hold the charger plugs when not in use).

Filament used is eSun PLA+ Peak Green.  Standard MK3S+ settings.  Smaller openings are approx 35mm dia, larger is approx 48 mm dia so it should fit drills similar to the Ryobi.
