Kobra S1 filter compartment refillable box

I made a refillable activated carbon filter box for the Kobra S1 printer. The fabric used is from the original Activated Carbon filter bag that originally came with the printer. I just cut it and glued it in. This box is a nice to have if you have a cheap supply of Activated carbon that you can swap out from time to time. Recommendations: Have a thin rubber or silicone layer on the edges of the backside to make a proper seal. Layer lines are a good escape for air, but you want the air to go thru the filter and not around it. Note: The box is slightly tapered on one side (as is the housing in the printer). Make sure to not force it in the wrong way. If you would like me to make more useful stuff. Consider supporting my efforts.
