This is a slide on for the Worx Android M500 Plus (and possible other models...). I have printed the new rear wheels I retrieved from another site and now the front wheel was a bit too low so I designed a slide that also provides a bit more grip. Preferably printed in TPU95A (PETG will do also as it's a bit flexible). Fits on front wheels with a 80mm diameter. There is a narrow and a wider version available.
