Customizable Brackets

**Customizable Brackets**

A collection of corner, flat angled, flat straight, and U-shaped brackets
with configurable angles and hole patterns.

Used by my muffin fan holder and mini greenhouse projects (see pictures).


**Updates**

Version 2, nov-29-2023:

- Add capability to specify corner-style brackets side lengths separately
and u-shaped brackets base and arm lengths separately. Note this
modification required changing the customizable brkts_bracket_length
parameter from a scalar to a 2D array. Please update your brackets.json
file accordingly.

- Add capability to specify which sides of brackets have holes for mounting
screws.

- The brackets thing longer includes files from the BOSL2 library. BOSL2
can be downloaded from github (see below).


**Notes**

- The top level OpenSCAD file is brackets.scad. This is the file you open
when starting OpenSCAD or the file that you pass to OpenSCAD on the
command line.
