Aurora Solar Inverter 80mm Fan Cowling

thingiverse

These parts enable an additional 80mm fan to boost the cooling of a heatsink on an Aurora Solar Inverter. For my installation, I utilized a 12V fan driven by its own 5W solar panel (with a simple 7812 voltage regulator & heatsink) since it only needs to run when sunlight is available. This setup reduces the inverter temperature by about 8 degrees, which should increase the longevity of the inverter. The fan direction pulls air upwards. Printer Settings Printer Brand: RepRap Printer: Mendel 3 Rafts: No Supports: No Resolution: 0.2mm for the first layer and then 0.3mm using slic3r Infill: Hexagonal at 20% Notes: Part 1 is the main fan cowl - 63.4 meters of 1.75 filament, print time approximately 8 hours Part 2 is the top exhaust cowl - 26.8 meters of 1.75 filament, print time around 4.5 hours Part 3 is the support flange (It is printed upside down) - 10.2 meters ~ 1.2 hours For my printer, I rotated the stl's 90 degrees on Slic3r to better fit on my bed. The largest part measures 174 x 94. How I Designed This I created these parts in TurboCad Pro and saved them as STL files.
