Active coal filter holder for 120mm computer fan

cults3d

3D printers melt plastic and it doesn´t smell so nice. To tacle this problem I have always had active coal filter by the printer. After moving the printer to a new place it was time to make a better filter holder. This one is a big one with a big area for the filter material. I use a active coal sheet made for over the oven fans. A sheet costs a couple of € and lasts for years. Thickness is 7 mm. In the bottom of the holder is a standard 120mm computer fan which is drawing air in through the filters (so that the dust gets collected on the outside of the filter. In the files is the complete holder + top and the holder cut into four pieces. I made it from the four pieces and glued them together.
