A bracket for the large IR sensor from Adafruit

This thing is a bracket used to provide enough surface area for using a double adhesive tape to mount the IR sensor against a surface. The IR sensor from Adafruit (http://adafru.it/1031) is hollow at the
back, which makes it unsuitable for double-adhesive-based mounting in its stock configuration.
A scad file is provided for changing options to adapt this thing to a sensor of a different size.
This thing was designed for the HackerspaceSG door sensor (https://github.com/miccheng/HSG-Door-Hack), which kept drooping and triggering intermittently due to being mounted using bluetack.
