Tension belt retractor - Spanngurtaufroller

thingiverse

To help myself in everyday life, I designed this device so that I can wind up my tension belts quickly and cleanly. This is a significant improvement over other models that had too many individual parts and the roll was not wrapped properly or the tool did not fit the width of the belt. This model is specifically designed for common 2.5 cm wide belts like [this tension belt](https://amzn.to/2Op5Hrd). The simplicity of this design makes it suitable for everyday use, eliminating the need to deal with complex mechanisms and multiple parts. The device consists of only two parts: a frame with the handle and crank. There are two versions of the crank available - a rotating handpiece and a fixed handpiece. The rotating handpiece is designed with a sleeve that can be rotated to avoid reaching around, while the inside of the sleeve is tapered so it cannot be removed. I tested the handle with 65% infill, which was more than sufficient for everyday use. The crank should be printed with 100% infill, then normal PLA is sufficient. I recommend using [this PLA](https://amzn.to/31jiGAb) or [this PLA](https://amzn.to/2GQt2xY), as they performed well in my tests. Fixing the straps with a [reusable cable tie](https://amzn.to/2UnXdV1) is also highly recommended. It holds better than rubber bands and does not become brittle so quickly.
