The holder is available in two sizes.
The normal version is for the box with 126 mm width and the large version for 147 mm.
I was able to print them easily with the 0.4 nozzle and 0.2 mm layer height without brim and with just an organic support in the middle.
Maybe some of you can use the model too =)
The author remixed this model.
This allows the nozzle box to be stored on the Skadis system.
