Compost Bin with 130mm carbon filter

thingiverse

I created this design as a result of having spare 130mm carbon filters that I had used previously in a solder fume extractor (https://www.thingiverse.com/thing:3921076). The carbon filter helps reduce odors in the compost bin, which is exactly what I wanted. However, printing it would be expensive, equivalent to buying a metal or plastic one from a store. If you need to extend your printer's build size, this design might be helpful.
