Copied PaulRac's fan mount design (from scratch) and adjusted it to mount a 30mm fan. Also improved it so the hot end does not need to be removed to mount it.Guarenteed to fit on a Printrbot LC wooden extruder with a 30mm fan. This mount is thin enough such that the stock extruder mount screws will work.Volume: .25 cubic inches ABS Weight: .01 poundsNotes: Use of a smaller layer size will improve results. No supports required. Print slowly, and use low temperatures, especially towards the end of the print.
