Hottop Coffee Roaster Chimney

thingiverse

This chimney fits on the vent end of a HotTop Coffee Roaster. This makes the smoke go up into your range hood instead of blowing sideways into your kitchen. Held in place by two pegs. Drill holes in the fan shroud, put the chimney on, and insert the pegs through the chimney and into the drilled holes. If you don't want to drill the holes, you hold the chimney on with gaffers tape (or duct tape). I did it that way for months and it works fine. The version with the sacrificial layer has supports and an extra layer under the roof of the chimney where the chimney meets the fan box. Remove this layer and supports after printing. Makes for a slightly cleaner print in my case. See the third image. This fits on an Ender 5. You could probably print in parts and glue together, too. I printed most at 0.3mm layers for speed, but used 0.2 where the curves are almost flat so it would look a little better. Two outline shell thicknesses are sufficient for rigidity. I used PLA and it tolerates the warmth without a problem.
