This Hex Key Holder is made for use with the Modular Tool Rail System. It holds five metric hex keys - the type you might get with your 3D printer. There are two versions of the holder included here. Additionally I have included the original Fusion 360 file (which is a bit messy) and an exported .STEP file.

The first is a single part, but requires supports. To print this use the file: OnePart.stl and add supports below the attachment dovetail.

The second consists of two pieces which can be secured together with CA glue or with m3 screws in the provided screw holes. This version does not require supports. To print this use the file: TwoPart.stl.
