OpenSCAD Challenge – Klein Bottle – the winners so far!
Klein Bottle from simple primitives by MakeALot
First, I need to preface this by saying I can’t believe I overlooked coasterman’s low-polygon count Klein Bottle posted about a year ago. Although created in Sketchup, this design is about as low-poly as you can get. Now! On to the imaginary awards show!
- First to upload that wasn’t me: MakeAlot with a Klein Bottle from simple primatives for uploading his designs within about 3 hours of the challenge being posted.
- Fewest lines of code: MakeAlot with a Klein Bottle from simple primatives with just 33 lines of code.
- Fewest facets: Low poly (but still) klein bottle by aubenc with just 40 faces!
- Most resembling a traditional Klein Bottle: MakeAlot with a Klein Bottle from simple primatives for his very curvaceous OpenSCAD designs.
Building on the work of these fine designers, can you design a Klein Bottle in OpenSCAD that uses fewer lines of code, has fewer faces, or is even more traditional looking?
A more traditional looking Klein bottle made from torus halves and tubes.

Quick, easy and dirty OpenSCAD to make a low poly klein bottle.
Ehem...
Quick? Not as much as I thought (1h-1h30)
Easy? Easy would have been using cylinders $fn=3 instead of polyhedrons!
Dirty? Yes! It looks like a parametric thing but it's NOT!
Low Poly? Neither, OpenScad reports 40 faces but there's some misalignment that's adding 4 more than needed.

Yes, I realize I declared this challenge and am entering it myself. ( makerbot.com/blog/2011/10/11/openscad-challenge-klein-bottle/ ) I didn't start designing this until well after I had already posted it. Since there are no real prizes, I figure you'll forgive me claiming the "first to upload", "fewest number of facets" and "most resembles either Kelsorj’s Klein Bottle ( thingiverse.com/thing:5217 ) or RotoScan’s Klein Bottle ( thingiverse.com/thing:11976 )"
The bottle could be rendered with even fewer facets by just reducing the number of faces on the cylinders in the OpenSCAD file.
Also, I hereby claim 9000 internet points! Mu-ah-ha-ha!
Also, a shout-out to CloudSCAD is in order for letting me draft this up from my browser.
