Light Pipe Adapter for Raspberry Pi 3 Model B

Remix of [Light Pipe Adapter for Raspberry Pi 3 Model B](https://www.thingiverse.com/thing:2773504) by LA2YUA to make it suitable for use with a [BitScope Blade](http://www.bitscope.com/product/blade/?p=index) - it replaces one of the corner nylon standoffs (which is just a hair under 10mm).

This also differs from the original in that it is designed for 2mm PMMA fiber.

This was intended to assist with the mount of a [BitScope Blade Quattro Pi](https://www.bitscope.com/product/BB04/) with an internal ethernet switch inside of a a [Bud Industries PRM-14460 1.75" (1U) Plastic Rackmount Box](https://www.budind.com/view/Plastic+Boxes/Plastic+Rackmount+Box) (a.k.a G17081UBK).
