Printable Tall Print Cooling Fan

thingiverse

To combat issues with small objects during printing, I created a fan cooler on Thingiverse (http://www.thingiverse.com/thing:4442). The device ensures that surface layers cool down before the next layer is deposited. During assembly, I discovered that taping a fan to plastic or paper was time-consuming, so I opted for bolting instead. The STL file accommodates a 40x40mm fan from an old VGA card. While the design has significant internal overhangs, printing proceeded without major issues and support materials. Post-printing, I considered using a 'cool' function to control fan activation based on layer time, but for now, manual M106/M107 codes will suffice.
