Vertex R8 Chuck Gridfinity Holder

A Gridfinity tray to hold my keyless chuck for my mill, in 2x5 squares.  Overall I am pretty happy with how this turned out.  Due to the mass of this chuck and its uneven distribution, I put access cuts at each end of the holder, so it can be removed using two hands.  In hindsight, I probably could have left the jaw end of the holder open, so the jaws wouldn't necessarily need to be opened all the way up for the chuck to fit in the holder.  If that's important to you, you can probably modify it in the slicer if desired. 

Like my other Gridfinity models, the base is altered to accept 6x3 magnets as a press fit, with the upper surface of the magnet holes modified to make the slicer bridge across correctly for a clean result.  Due to the size of this model, I have included sacrificial “mouse ears” in the CAD to give the ends more surface area to help prevent them warping off the bed.  These will need to be removed after printing.

The unit pictured was printed out of Overture PLA on my Bear upgraded Mk3S+, using a 0.6mm nozzle, at 0.3mm layer height.
