### Rolling Knife Sharpener with inbuilt planetary gearbox with Mechanical Advantage of 1:3 (HORL compatible) >**Important:** This part is published under the Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0) licence!

Full CAD-Files: See attached .step file. Printed in PLA with a 0.2mm Nozzle. This project is work in progress. Currently known issues: * The space for the outer planet gear holder bearing is too large, so the rolling disk wobbles a bit axially after assembly * I work on a version that works with 0.4 mm nozzle, though this is difficult, and the result will be worse * I work on a version, where the two sides are not connected for better curved knife grinding I will update this when I find the time to work on those issues. With 0.2 mm Nozzle, the currently uploaded version works very well, though.
