**New Improved Version uploaded (BitHolderVerson3).
Bit holder designed to fit into Dewalt Hex Bit storage cases. As you can see in the pics, Dewalt hex bit kits come in these storage cases that have a certain dovetail pattern in the sides. This model allows you to add and/or improve the storage adapters in the case. My version is somewhat improved over the original because it has a rotation capability built in. I find it much easier to put my tool bits or take them out with this version.
These are best printed in a strong but flexible material. I used a black "Flexible TPU" from Sainsmart that worked quite well.
