These are components which I designed to work in the festool/tanos systainers. I was in the works of getting these available injection molded through Fastcap and they backed out of the deal. So I figured I would make they available to all who want to print them.
Also there is a domino Dowel Jig. This get set into the groves of the Domino Centering guide and can be used to place a domino centered at the end of a dowel. There is a little v notch which helps on centering it into the guide.
I make MFT templates available at Woodrave.com for those looking for a solution to build their own MFT tops.
I recommend printing these in ABS. 2mm layer height is good.
