I created this model as a fun way to spice up you kitchen.  It can hold 9 knives all up to a length of 250mm max(9.8in).  I have not had time to print this, but I will definitly update this if I do.  The size for this should fit on a MK3S+, but a skirt will not be possible.  Able to be slightly scaled down if needed, but not much because that will make the tolerances for the width of the knives tighter.  This model is remixed from a minion on thingiverse, and I will link it below. I could not find it on Printables.
