4 PIECE DRIVER SET HOLDER (1.5, 2.0, 2.5, 3.0) 

I have seen a few of these floating around, but they didn't fit the ones I bought from Amazon nor were they stackable.

I made this model from scratch to be stackable, easy to change colors when slicing or print in a solid color. 

Added a flat indexer to the floor so the drivers identity always faces up.

*Fits tools up to 180mm Long.

Note: The original Gridfinity system was developed by Zack Freedman. Big thanks to him for this wonderful design.
