Dust filter redesign from dust filter of IRolbertl. I like the design and the idea of IRolbertl for a dust-filter but during testing I figured out that the function (clipping, correctly closing, alignment) depends much from the flow you used during printing. After a lot of tries I got it working more or less properly. For improving my design skills I tried to make my own version with a different kind of clip. This clipping works so good that I decided to make my first share ever. Maybe somone has the same problems. So if you have problems with IRolbertl-design clipping correctly with good alignment you can give this version a try. Nevertheless thanks to IRolbertl for this great idea.
