Dodeca Chain Loop
by emmett, published
This chain of 40 interlocking rhombic dodecahedra forms a loop that covers nearly the whole Replicator build platform. It's not quite big enough to be a necklace, but it can work as a crown or other decoration. It's quite fun to play with.
The OpenSCAD file is parametric, so if you have a different size build platform, you can adjust the dimensions of the loop by changing the number of modules in the straight section and scaling the whole.
This design is a good torture test of skeining engines and printers alike. It has a flat bottom, less than 45 degree overhangs and all the bridges are straight, yet the small features make it a difficult print. Good luck trying Skeinforge; this was skeined with Slic3r, which worked, but it also demonstrated some bugs and features that are not quite up to snuff. If anyone can show me a skeiner that does a better job than Slic3r, I'll be duly impressed.
