This is a remix from Xathorron https://www.printables.com/model/261588-kreg-pocket-hole-jig-310-case
Its a holder for Kreg pocket hole jig 310 to work with Gridfinity. I ended up designing 2 different models. one is shorter (5u or 38.8mm tall) and one is taller (6u or 45.8mm tall). Created the taller one after I found out the jig sticks up above the 5u by a few millimeters, and I wanted to be able to stack other 2u wide boxes on top of it.
The author remixed this model.
I adapted Xathorron's Kreg Case to work with Gridfinity
