Description

This is my copy of the famous Szilassi polyhedron, resized for RepRap printers, including the Huxley.
This unusual mathematical shape has the topology of a doughnut but using only 7 faces and 14 edges. Each of the 7 faces shares an edge with every other face, proving that 7 colours are required for mapping on a toroid.

Instructions

This printed beautifully until the apex of the model, when the excessive heat from rapidly printing the last few layers caused the tip to wilt a bit. I'm looking for a way to improve this flaw.

Thanks for this thing!!!

After printing up several of these, I crafted it's dual the Csaszar polyhedron: http://www.thingiverse.com/thi...

...marked as a derivative of this thing, and my very first thing on thingiverse! :)

Please if you can, draw the dual of this. I made this one but I don't think I can draw the dual.

It only proves that you need at least 7 colors ;)

You can fix the excessive heat on the last few layers problem by using the "cool" plugin in skeinforge. Basically, what the "cool" plugin does is, if a layer is going to take less than the specified amount of time to print (based on the minimum layer time setting, I set mine to 15 secs).... it slows down on that layer to allow it time to cool.

Another solution is to use a fan. Or you can get really basic and just blow on the print for the last few layers, which usually results in dizzyness.

I found the fan to work best. The Cool plugin just made a different kind of mess. :-P
