Shorter version, 43mm to fix collision issues. No z-resize, it was cut and 4mm were removed.
K1 max has 45mm distance between the nozzle tip and lower rod (see slicer config for your printer). The original model is 47mm. This means when printing vase+sequential the model will collide against the lower x-rod if you have 2 next to each other. So you are limited to 3 pieces per plate (1 per row).
This version is 43mm and fits under the rod, you can have 9 on your plate without collisions. In case you need many :-)
The author remixed this model.
