About the Klein Bottle:
History: First described by German Mathematician Felix Klein circa 1882. (source: Wikipedia) Wikipedia describes the Klein Bottle as an example of a non-orientable surface. A two-dimensional manifold against which a system for determining a normal vector cannot be consistently defined. Informally, it is a one-sided surface which, if traveled upon, could be followed back to the point of origin while flipping the traveler upside down. ...
For my part, I am looking at odd-ball geometric projects that I can print in 3D. There have been other geometric objects so far, but this Klein Bottle sort of struck my fancy.
Notes about the 3d printer. I am using a consumer grade FDM (fused deposition modeling) printer based on the Pruisa RepRap design. Cost of this printer was low. Cost of the filament, either ABS or PLA, is not expensive either. What this does is allow me to produce a solid object I can hold in my hands created from what I draw within my CAD software.
PS. not about audio and it's binary, I think.
PSS: about the printer.
3d printer is mfd by CTC in China. Sold in a kit where buyer must assemble. Assembly in and of itself was a journey. (my first one) I bought over eBay in September 2016. Price was low then. For this model it's now less than half the price I paid. Printer model: (as described in the owners manual and eBay sales sheet: Reprap Prusa i3 DIY 3D Printer. Capacity: 200x200x180mm
The software----- slicer software --- Cura was included. I use it in combination with Repetier Host V 2.1.6. I print from an SD card.
