About this 3D model

Part fan for Peter Stoneham's Rigidbot Dual V6 Mk8 Alloy Mount. Fits both version 1 & 2. This fan mount takes advantage of the existing bearing bolts as well as the extra mount point on the far right edge (M3) to minimize sloping. Consists of two parts in order to get perfectly flat bottom parts closest to the print bed, as well as to the carriage. The parts fit together with M3 bolts and nuts - or super glue if you want to keep the weight to an absolute minimum. Uses a single 40mm fan to cool part for both extruders. UPDATE 2016-01-27 (v2B) Increased distance to bed, will not hit printed parts on fast moves Improved airflow with wider distribution, better downward angle Centered fan in relation to print heads (X axis) Centered fan in relation to mount (Y axis) Stronger mount points Better weight distribution UPDATE 2016-01-31 (v2C) Redesigned nozzle to force air more downward, away from heater block Larger flat bottom area for easier printing, slightly larger air volume Fixed small alignment issue on fan mounting holes
