Lack stacking remix for Prusa mini, leg extension

This is a remix of the nice lack stack adapter.  It is just 50mm higher to allow for the prusa mini to fit.   I have been printing taller items lately and found that the bowden tube and wire harness were rubbing on the bottom of the next shelf.  

I just made a new model based on the dimensions of the original. I wanted to add something in the extended part to make it more interesting, so I added a hole.  Hex shapes are popular right now so why not?  Then I had a 1 inch (2.54 cm) dowel at my desk and thought that it would be functional to make the hole fit the dowel.  This way I can add a stopper in the back, or bridge shelves to hang things, or even the beginning of something to hold acrylic for an enclosure.  

It prints the same way as the original, and the printer just bridges the gap.  no need for support material.
