Groan Sphere

It begged the question though: "what to do with a 20 sided object?" Clearly I needed 20 things and unfortunatley Amazon is more than happy to sell cheap junk next day delivery.

Groan Icosahedron 1

To attach them was simple, add holes to the model for a press fit. Global Variables came in clutch here as no one would be so foolish as to enter all the dimensions by hand the first time around and then find out the actual 3d print didn't quite hold the tubes (right?)

Finally if I wanted this to roll around, and unfortunately I did, I needed to add feet to the other side of the groan tubes. As I was going to be printing 20 of these I needed to keep it simple.

One is the lonliest number, and three was far too peaceful for this operation - so two was the right number of center connections for the final design.

Now eagle eyed viewers will probably join me in the disspointment that while the icosahedron itself is a perfect shape, expanding it in such a way leads to dead spots above each of its 12 verticies... on to round 2.

UPDATE: Introducing the Groan Sphere 2, with a 60% increase in sound density it is even more obnoxious than before! 

As mentioned previously, there was an opportinity to increase the noise density of the groan sphere - and I was obligated to do it.

33 prints later and here we have it - perfection.
