Optimized for support free printing and maximum mechanical usability.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 assemblyI work on a version that works with 0.4 mm nozzle, though this is difficult, and the result will be worseI work on a version, where the two sides are not connected for better curved knife grindingI 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.Assembly GuideIn this document, you can find a description about the assembly process and needed tools, parts and settings of your printer:https://drive.google.com/file/d/1ADHG-sUP8cmbcfGfjGgHIIo4i02iNEqt/view?usp=sharingNeeded Materials Bearings 3x15mm × 24mm × 5mmLink:https://www.amazon.de/gp/product/B07KFSMR6X/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1or similar2x35 mm x 47 mm x 7 mmLink: https://www.amazon.de/gp/product/B08LK7H7JJ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 or similar1x30mm x 42mm x 7mmLink: Original Link Expired, alternative: https://www.123kugellager.de/lagern-6806-2RS?gclid=CjwKCAjw7vuUBhBUEiwAEdu2pMMBQ75UwnJxFekbPx3aBs_2ggvOOHqqxFkcMtEHTygKeXOmEhmhChoCzWsQAvD_BwE 12x3mm x 10mm x 4 mmLink:https://www.amazon.de/gp/product/B07CWLGNJ5/ref=ppx_yo_dt_b_asin_title_o06_s01?ie=UTF8&psc=1Screws and Threaded insertsScrews:8x M2x81x M4x143x M8x8Threaded Inserts (Ruthex):2x M61x M43x M3S (Short Version)2x M2see https://www.thingiverse.com/thing:4682424For further details, please take a look at the assembly guide. MISC2x G3/8" flat seals, e.g. https://www.amazon.de/gp/product/B08TZZGPVZ/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=12x 50x4 mm O-Rings:https://www.amazon.de/gp/product/B00N3UZ0SG/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=16x 3x20 mm steel pins:https://www.amazon.de/gp/product/B07YKND8QW/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&th=1This model on Thingiverse: https://www.thingiverse.com/thing:5391756 I would love to get Feedback if anyone attempts a Make!
