This is a holder for a NOVA Midi Chuck and the 4 piece Teknatool jaw set, and all associated screws and tools.

It holds the chuck in the middle and then the original jaws and the Teknatool jaws around the outside.

It also has insets for the 8 screws, the 2 handles that operate the chuck, and the 2 Allen wrenches (the small one for the set screw and the larger one for the jaw screws). I also added holes for two other random lathe tools I have.

This is a huge print, and it took 57 hours on my Ender 5 plus.

The OpenScad file is included, and you can add a base to it, which will add another 4 hours or so to the print. I didn't see the base as necessary, though I originally designed it that way. Just uncomment to print with it.

It is somewhat parameterized, but not at all perfectly. That is, there may be no easy way to size it up for a larger chuck and jaw set.

You might can get a faster print with a lower infill or resolution. I printed mine pretty high and 6 outer layers just to make it a bit tough considering the weight of the metal it holds.
