A simple knife holder, with six slots of variable width. I made it mainly with IKEA 365+ knives in mind, for which I couldn't find a suitable holder. I made the whole thing with a main block made of PLA, inserts and a base made of ABS. I recommended making inserts with thicker walls to improve their resistance to damage during use. It is best to make the main block with biger infill for better stability.
It is best to print everything upside down, without any support.
