Deprecated: MCAD replacement for nuts_and_bolts.scad

#NOTE:
##This thing has been deprecated and replaced with this: http://www.thingiverse.com/thing:1259672

Replacement library for the OpenSCAD MCAD nuts_and_bolts.scad library.

Also see this superior nut and bolt library.

Import this library into your OpenSCAD design:

include </path/to/libraries/nuts_and_bolts.scad>
mBolt(m3);

Because of the lookup functions you will need to use import instead of use. Make sure
you comment out the simpleDemo() line as well.

This library provides metric series fasteners in the following sizes: 2, 3, 4, 6, 8, 10, 12. Additional sizes can be added easily.

The following fasteners are provided:

• M Bolts with hex socket and hex heads
• M Nuts (standard only, no thin)
• M Washers
• T - Slot cutouts for laser cut joints

NOTES

• This is NOT a drop in replacement for the MCAD library, but rather an extension with more features
• OpenSCAD 2015.03-2 crashes HARD if the called m bolt size does not exist due
  to a bug in the lookup() function. A bug report has been filed and should be fixed
  in the next release: https://github.com/openscad/openscad/issues/1528
