Parametric Straw Connectors (OpenSCAD)

These Straw Connectors can be used to link together straws into big structures. For fun with kids, but also as a frame to wrap in rice-paper and use as lamp-shade, or any other application that needs a light-weight structure.

The files contain a few sample STL files for some possible connectors, but the main source is the OpenSCAD file, which makes it easy to create any size and type you want. See _Parameters_ for details.

The sample files and default parameters are tweaked for use with the big IKEA straws (Sötvatten). Other brands of straws might work just fine.
Because the connectors require a press-fit and straws don't stretch much, an exact size of the connector is quite critical. Different straws and different printers and printer settings may lead to slightly different fit. Print a single XYZ connector first to test-fit, before printing a grid of multiples connectors.

Full disclosure: This is not my own original idea. The concept exists (or has existed) commercially,
