Add support for indented bottom to save filament #80

Adds support for indented bottoms for bins by setting style_hole to 4. Indented bottoms reduce the amount of filament required to print bins. Does require your slicer to support bridging.

Here's an example of the bottom of a 1x2x4 bin printed with this option: image image

I do like the idea and it looks very good. You say it reduces the amount of filament required to print bins. I think this highly depend on the slicer settings. I checked and saved a 0.02g of filament per bottom block (10% infill, 1 perimeter). In my opinion this is not worth the risk of these large overhangs and the reduction in bed adhesion.

Which numbers do you get?

Possible better solution: slice with zero bottom layers such that you just have exposed infill that reduces filament and supports the bin bottom. This also reduces the tendency of the corners to lift off the bed as the solid bottom layers are printed. IMG_1082
