Mower Blade Balancer

I was excited to find a lawnmower blade balancer on Makerworld and I happily printed it without checking the hole my Bosch AdvancedRotak blades have. Obviously, the initial balancer didn't fit. So now I've remixed that model and added a few extra rings to extend its compatibility. Isn't 3d printing great?! The rings start at 4mm diameter and they increase by 4mm with each level, so you have 4mm, 8mm, 12mm and so on. If you need a custom diameter, the easiest route is to download the STL, import it into Tinkercad (web) and add more cylinders. You can cut the object to intertwin them, in case you want to increase the radius of by only 1mm.
