Summary That is a new, two-sides fan duct for Anet A6. All what you need, just rotate your original fan. In my other thing, I was made platform for rotated fan already (fan_v4_platform.STL). Print Settings Printer Brand: RepRap Printer: Anet A6 Prusa Rafts: Doesn't Matter Supports: Yes Resolution: 0.32mm Infill: 20% Notes: Be careful, nozzles may be brittle, their walls are thin Sources Sorry, but I'm still newbie in Solidworks app, so the project is not very well for publishing >_<
