Filament Guide + Dust Filter for JG Aurora A3

I remixed the JG Aurora A3 Filament Guide made by varind to provide something to place a sponge or such as dust filter.

Furthermore I added a small piece between the gap, so that it can be printed completely without support. In the original version support was needed, that took more material and was hard to remove.

I added the original files, so you can download the openscad-file (even though it does not appear properly on thingiverse) and modify yourself.
