Carbon Filter Holder for Kotto Solder Smoke Absorber

thingiverse

Here are two replacement holders for the carbon filter in a Kotto "Solder Smoke Absorber" - the model with a flexible hose. The first one is a straight replacement for the cardboard holder that comes with the unit, but with some tabs that project upwards to make it easier to remove from the machine. The second version is an attempt to redesign the holder so that the air will flow more evenly through the entire cross section of the carbon filter and use the filter more evenly. (I noticed that the original design tends to concentrate the air flow in the middle of the filter, so that it would probably need to be replaced sooner.) This new design has not been tested enough to confirm that it is better than the original.
