Prowin "Wini" Vacuum cleaner rear-wheels fixation

thingiverse

One issue which I always had our vacuum cleaner was, that all 4 wheels were rotatable for 360°, which lead into a very unstable path of our cleaner when pulling it after you. Because of this, already some walls are damaged in our house. I have printed "fixation-pins" which fit inside the original housing and wheels of that cleaner. Just pull off the original (rotatable) wheels (no big force required...) and put the "blockers" inside it and align the wheels accordingly when putting it back in its original position. Due to this fix, the rear-wheels will not turn any more an the path is way more stable. Your walls will love it. The included STL file is for the left side only, for the right side, you just have to "mirror" it with our slicer (I used Cura 4.8 for this). Print it in the way like shown in the pictures, you need supports!
