Mini Fabrikator (Tiny Boy) - Filament cooler

thingiverse

This is a totally reworked "TinyBoy Blower Filament cooling fan" originally created by "wkkpatrick" (http://www.thingiverse.com/thing:1157073).\nDifferences from wkkpatrick's version:\nIt is approximately 3 mm longer and it positions air output hole down for 3 mm, avoiding the hot end cables.\nThe air output hole is slightly narrower - 2.5 mm\nIt redirects more airflow from the fan, 15 % of fan surface area\nAs you can see from the final picture, this cooler is not really capable of printing longer bridges. It works perfectly with small gaps.\nRuler units are in millimeters. The left bridge had the fan blowing parallel to the bridge, while the right bridge had the fan blowing perpendicular to it.\n 1.1 Increased filament cooler air intake significantly. 1.2 Added some minor edge fillets.\nPrint Settings\nPrinter: \n Mini fabrikator 1.5\n \n Supports: \n None\n \n Resolution: \n 0.2mm\n \n Infill: \n 40%\n \n Notes: \n Printing speed is 18 mm/s at a temperature of 200 C
