Dyson V10 Soft Brush Bearing Cap

thingiverse

Recently I've encountered an issue with my Dyson V10 soft brush tool, where something was stuck inside after repeated use. Following a thorough disassembly, I discovered that one critical component had broken completely - it turned out to be the bearing cap. The brush roller's design features one end connected directly to a motor spinner, while the other rotates freely - this is precisely what the bearing cap is intended for. To address the issue, I decided to print a replacement part and test its functionality. Fortunately, the new bearing cap worked seamlessly! However, it's essential to note that printing this part requires utmost precision to avoid any potential problems during assembly. One critical aspect to consider when printing the bearing cap is the diameter of the inner hole. If it's too small, you risk breaking the outer walls of the bearing while attempting to fix it in place. Conversely, if the diameter is too large, the bearing may not fit securely. Given that every printer and filament combination can vary slightly, it's crucial to adjust the print settings accordingly. For instance, you might need to tweak the diameter by a mere 0.2mm to achieve optimal results. I've outlined my own step-by-step process for printing this part in the following sections. When printing the bearing cap, make sure to orient it correctly - with the side ear pieces and holes facing upwards. This should help prevent any potential issues during assembly. As an added precaution, you can also print without supports, as they are not necessary in this case. Before embarking on this project, remember to unplug your Dyson V10 from its power source and take necessary precautions to avoid breaking any components. While I've had success with this method using the V10 soft brush tool, it's unclear whether this approach will work equally well with other soft brushes or models. If you're willing to try, good luck!
