This is a mostly printable device for sharpening knifes using DMT Diamond stones. It uses hardware I had laying around so it's more or less built around those parts.
Parts needed:
DMT Diamond Stones
Linear rail - in my case HIWIN from an old 3D Printer
Steppermotor and Driver - and some sort of controller that can make it spin forwards and backwards. In my case an Arduino nano and a SilentStepStick
An O-Ring to increase friction of the pulley
M4 heatset inserts
M3 screws to fasten the Stepper - I also used them to fasten the linear rail
Some screws to fasten it all to a wooden plate
I printed all in PLA and it works fine! The only part that needs little support is “jaw2.stl”
There is the option to use a sting, that wraps around the “Pulley.stl” and gets fixed at the ends of the “Stoneholder.stl” but I prefer the use of “pulley2.stl” and an O-Ring that rides underneath the “Stoneholder.stl”
To set the sharpening angle i use a Smartphone app called “Bubble” (Fdroid store).
This is a one weekend build inspired by This Old Tonys Video about sharpening knifes, where he uses some accesories from a Tormek sharpener. I dont have those accesories so i tried to make it all 3D printable.
Feel free to ask questions in the comments or request some changes. But I can not guarantee to put more work into this.
Here is TOTs Video (it's very good):
