The diameters of the design file are 10mm and can be scaled to any diameter. Eg – if a diameter of 11.6mm is required, just scale the part to 116%.

This ‘tripod’ orientation for printing makes the diameters more uniform.

The large straws in this model have a nominal diameter of 12mm. For this pack of straws which I obtain the internal diameter vary between 11.3 to 11.8 mm for different colors.

The length of the straw for each side of the cube is 24mm. Please scale the length if using a different straw diameter.
