Updated Dec 2014 by Paul Hutchison - additional box options for 2,3,4,5 sides and internal dividers
Updated June 2015 by Paul Hutchison - Inkscape 0.91 compatibility, more logical defaults
Updated July 2015 by John Slee - Added Schroff enclosure generator option. Currently 3U rows only.
## About
This tool is designed to simplify and speed up process of making practical boxes using a laser cutter (though it can be used with any CNC cutter) to prepare the pieces.

## To do
* Tidy the code - it is rough and unpythonic. Needs some work by a master Python guru.
* Improve program documentation. Improve input checking to restrict values to correct solutions.
* [Schroff] Maybe replace the somewhat obscure collection of Schroff rail input data with a dropdown box listing well-documented rail types (Vector, Z-rails, whatever it is that Elby sells, others?)
* [Schroff] Add support for multiple mounting holes per rail where possible (this would definitely make the previous todo item worthwhile)
* [Schroff] Add support for 6U row height
## Use
## Use - regular tabbed boxes
The interface is pretty self explanatory, the extension is 'Tabbed Box Maker' in the 'Laser Tools' group ( hopefully more tools will soon{ish} join it ).

* Space Between Parts - how far apart the pieces are in the drawing produced
## Use - Schroff enclosures
Much the same as for regular enclosures, except some options are removed, and some others are added. If you're using Elby rails, all you'll need to do is specify:
* Depth
* Number of 3U rows
* Row width in TE/HP units (divide rail length by 5.08mm/0.2")
* If multiple rows, inter-row spacing
## Installation
