Customizable Brackets

Description

**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). **Customizable Parameter Notes** Interior angle (default = 90 degrees) - this is the corner bracket angle which is typically 90deg. A smaller angle opens the sides up relative to each other. Bend angle (default = 0 degrees) - applies to the flat angled brackets only. Bends one side up or down from a flat surface. Can be used, for example, to join a flat piece and an angled piece on the top or bottom. Mounting hole (shaft) diameter, head diameter, head height - default to the dimensions for an #6 wood screw. Hole count (default = 2) - number of holes per side. Holes out (default = false) - flips the beveled screw head cutout to the opposite side of the brackets. Hole skew (default = 0) - skews adjacent holes relative to each other in the Y direction. **Greenhouse Notes** The top angled part of the mini greenhouse is 3' wide and 1' tall in the back, so the angle in the front is atan(1/3) ~= 18.5 degrees, making the angle bracket internal angles 90 - 18.5 = 71.5 and 90 + 18.5 = 108.5 degrees. See the upside down picture of the greenhouse frame to see how the brackets were used to support the frame. The angled flat surface bracket was used as additional support on the front greenhouse sides. It's internal angle is 71.5 degrees. **Included STLs** I've only included the STLs that I used for the mini greenhouse project. For other configurations, you'll need to use the OpenSCAD customizer (see below) **Customizer Notes** The Thingiverse customizer does not work with this thing. The Thingiverse customizer seems to be stuck at [2015, 3, 0] (the last time I checked anyway) and this thing uses some of the more modern OpenSCAD features. To customize, download all of the thing .scad files into a folder, then open brackets.scad with OpenSCAD. OpenSCAD is downloadable from openscad.org. **Licenses and Attributions** brackets.scad, et. al: LGPL v2 BOSL2: BSD 2-Clause License Copyright (c) 2017-2019, Revar Desmera units.scad: from the OpenSCAD repo in libraries/MCAD, Dual licenced under Creative Commons Attribution-Share Alike 3.0 and LGPL2 or later
