Hoi ! I found some Knife sharpener guides / Slides here. I Printed one and was kinda disappointed because the force the slide needs to be moved without any additions was too high and got stuck every time. The problem was that the slide was geometrically overdetermined. Also the dimensions of the rack was too big for my printing platform.

So I decided to make my own sharpening Guide/slide

All parts are 3D-Print-Friendly. No supports needed.

The Base is made of two identical parts wich are clipped into each other. I made different Angle slides 15° 17,5° 20° and 22,5° wich should cover all the main household and pocket knifes.

The Base is made for an Whetstone 180 x 60 x 30 mm (L x W x H) I Added an adapter plate for a Whetstone wich is 150mm in length.

I recently made a smaller one on request for a whetstone of 150x50x25mm here:
