Rolling grinder a la Horl. Holder has angles for 15 and 20 degrees (afaik 15 is recommended for higher-quality knifes, 20 for softer steel). I bought discs with 400 and 1000 grit (one for getting the basig angle, the other for actual sharpening); after testing, I'd probably go even higher (600 and 1000).
Non-printed parts
- 2x O-Ring R32 (50 mm inner diam.)
- 2x 608zz/608 ball bearings
- 2x Diamond whetstone discs (I bought mine here: https://www.aliexpress.com/item/1005005816085556.html)
- 4x magnets 10 mm diam, 3 mm thick
- Optional: 4x magnets 6 mm diam, 3 mm thick
- Optional: Thin rubber mat to glue over the knife holder (to avoid scratching the knife)
Printed parts
- 1x knife holder
- 1x rolling body
- 2x disc holders
Print with supports as oriented; I used 20 % infill.
Assembly
All parts are press-fitted. The disc holders' mount for the bearings might be a bit tight and require some sanding. The magnets most likely require a drop of superglue.
In my print, the grinding disks are held in place just by pressing them in. If they are to loose, you can insert magnets into the holes.
