Quick-use Dust Filter

If you are like me, you often forget to put the dust filter on your filament before inserting it to your printer, then you spend time removing it, putting filter on and reinserting it. This design shoud solve this problem, because it can be applied anytime, even during the print.

To set it, you need to print both parts of the filter and put some sponge into each part. Then put both parts together and use the knife or any blade to cut it along the gap. To apply it on the filament, just slide it through the side of the filter and twist one part of filter to side. It will lock it on the filament and if done correctly, it shoud be as easy to remove it.

This filter is still in prototype stage, so please leave your thoughts to help me improve it.
