Protective covers for 3M 6035 filters

This is a small mod for 3M 6035 filters that cover three purposes:

1. decorative thing - customization for your filters
2. protection - protects original unplugable cover from contamination
3. rain protection - probably the third cover's skirt could prevent filter from becoming wet.

All covers mounts on double-sided tape.
USE IT ON YOUR OWN RISK: it's not increasing main protection abilities of filters.

Fusion 360 file included, so feel free to adjust it.
