1 Useful 3D printing tools
2 ========================
9 *(if you gold plate for eg, or use expensive paint :))*
15 - *degenerate geometry*
20 - - self intersections
22 - - non-contiguous normals (bad flipping)
28 - basics - stray verts, loose edges
29 - degenerate faces, bow-tie quads
35 - visualize areas of low wall thickness.
36 - visualize overhangs (some printers have this as s limit).
37 - areas of low wall thickness.
38 - sharp/pointy surface.
44 - add text on an object *(common tasks - lots of people want this to add a name to personalize items)*
45 - Rig sizes (rings also common item to make)
52 - nice UI with format select and output paths for the print.
53 *no need to recode re-use existing exporters, maybe recode some in C if too slow.*
56 Integration with toolplating
57 ----------------------------
58 *(the thing that gets the model into printer commands)*
61 - https://github.com/makerbot/Miracle-Grue/blob/master/README.md
62 - Use a sliver, like slicer, skeinforge, cura, kissslicer, netfabb, ....
64 ...not sure yet exactly how this would work, but we could have a `Print` button and it would send the file off and print :).
70 - Normals are important
71 - Self intersections _can_ be ok.
72 - Some printer software already prevents solid areas from taking too much space by filling with non-solid grid.
73 *(So we may not have to care about solid shapes so much)*
75 - For extrusion printers like makerbots it is really hard to print "overhangs"...
76 because they build "from the bottom up" they can't for instance make an arm sticking out of a character sideways
