SummaryA silent triple 40mm setup with nicely guided fan duct / shroud.Print SettingsPrinter Brand: RepRapPrinter: P3SteelRafts: Doesn't MatterSupports: NoResolution: 0.1 - 0.3Infill: 10%Notes: Had to tone down the amount of solid infill in slic3r for the first few layers. I could not leave it at 70mm², had to set it to ~20mm². Else the print head would start to dig into the layers. YMMV. Cura sliced them up perfectly though. Needed a pretty large brim to keep it from lifting!Post-PrintingUse super glue to bond the 3 parts together. You have some room to fine tune the distance to the bed / print head. You can either hot glue the fans in place. (Dont worry removing them will still be relatively easy.) Or you can tap some M3 sized holes and use M3 12mm hex nuts to secure the fans.Assembling and mountingHow I Designed ThisUsing blender and DWONH's design
