How reliable is the design and in particular the blade holder? Share your using experiences.

It's rather weak if you use ABS. Maybe PLA will be better.

Does anyone know a good container to store the grinding stones?
They are really cheap(Chinese) and I have a lot of them in different boxes.
Nearly all have a part made of plastic which is bent heavily. I removed it and made one of solid aluminium by myself. Then I gued the grind stone on it. 2€/$ and 20 minute of work for a very good grind stone.

I would love to see them in nice boxes with printed labels....

i would like this to be locking by two magnets in opposing sides, would make a stiffer hold. And probably would loose a little bit of play.

hi I made this sharpener. This one lets you get even closer to knife because it is held by magnets so you can get steeper angle : https://www.thingiverse.com/thing:2753646

What did you design it in, is it possible to get the original files?

Nice thanks! I managed to download the stuff as SolidWork files, and then convert them to Inventor, cheers

Hi, I started to print this, but I found out that these knife clamps are missing :/ Could you please add those, thanks :)

Hello! My apologize about that. I added missing clamp stl. Thanks
