I have two kitchen knifes I want to store in the drawer but their edges would be damaged by the other utensils in there. I found this model but it's way too thick and massive for my knifes so I decided to create my own.

One of the knifes I want to protect you can see in the picture.

I suggest you download the sample file, print it, and test if it fits your knife.

This model should be easily scalable length wise but the corner cutouts will stretch a bit, shouldn't have any negative effect though. But if you need longer/shorter or thicker versions, just leave a comment and I'll try to upload a modified version.

Printing

  • Material: I used Extrudr PETG for a bit a flexibility, not sure if PLA would work.
