The file 'Fan-organ-pipes 3D Printer Model' is (FCStd,stl) file type, size is 1.4MB.
This collection is for a cooling fan powered organ pipe. The base is scalable via the spreadsheet in the provided FreeCAD files. This is meant to be used with a 12v fan and 2" Schedule 40 PVC pipe.
Both 1.5" and 2" STLs are provided along with the FreeCAD files for personalization.
The labium is based upon a Recorder labium. The large size is designed for low frequency tones.
If you modify the circumference for smaller PVC pipes, you will need to adjust the segments and airway path accordingly. This can be done from the spreadsheet settings in FreeCAD.
I have printed using PLA and had good success with the 12v fan.
