This is a remix of mz4250's excellent Tridrone model found here:

This remix is a fully assembled version of that model, thickened and supported so that it will print all as one piece on an FDM printer without (hopefully) breaking. In many print tests, it seems quite sturdy, although clearly it lost a lot of detail during the thickening process. I could probably have not extruded the model quite so much, but I was tired of printed failed tests so I overcompensated a bit.
