* Miscellaneous constants used in Mendel
* by Vik Olliver 29-03-2010. Uses components of the
* OpenSCAD Shapes Library (www.openscad.at)
* Copyright (C) 2009 Catarina Mota <clifford@clifford.at>

* 5-Apr-2010 vik@diamondage.co.nz
* Different clearances are being implemented for vertical and
* horizontal holes, as rudimentary extruders cannot relaibly
* control extrusions around corners.
*
* 5-Apr-2010 vik@diamondage.co.nz
* Added vertex separation and adapted for Y motor bracket.
