1 Useful 3D printing tools
2 ========================
8 - *degenerate geometry*
11 - - self intersections
17 - degenerate faces, bow-tie quads
23 - sharp/pointy surface.
29 - add text on an object *(common tasks - lots of people want this to add a name to personalize items)*
30 - Rig sizes (rings also common item to make)
37 - nice UI with format select and output paths for the print.
38 *no need to recode re-use existing exporters, maybe recode some in C if too slow.*
41 Integration with toolplating
42 ----------------------------
43 *(the thing that gets the model into printer commands)*
46 - https://github.com/makerbot/Miracle-Grue/blob/master/README.md
47 - Use a sliver, like slicer, skeinforge, cura, kissslicer, netfabb, ....
49 ...not sure yet exactly how this would work, but we could have a `Print` button and it would send the file off and print :).
55 - Normals are important
56 - Self intersections _can_ be ok.
57 - Some printer software already prevents solid areas from taking too much space by filling with non-solid grid.
58 *(So we may not have to care about solid shapes so much)*
60 - For extrusion printers like makerbots it is really hard to print "overhangs"...
61 because they build "from the bottom up" they can't for instance make an arm sticking out of a character sideways
