Replicape Kossel Mini holder

Description

This is a sunken placeholder for the Replicape and its BeagleBone Black that fits on the inside of the top frame. I sunk the frame a bit from the edges because I wanted to be able to use ChrisParish's spool holder (http://www.thingiverse.com/thing:454808) on top of the electronics. The original design was created by Elias Bakken, the creator of the Replicape, but his design would only be printable from an i3-sized bed (200x200mm), you couldn't print it in one piece on the standard KosselMini's 17cm diameter bed. This is my answer to the issue. Three parts instead of one. The three parts are held together by the screws holding down the BeagleBone.
