Tarantula X Carriage Mods Drag Chain attachment, BLTouch, Fan

The initial challenge I tackled was figuring out how to install a BLTouch sensor on the 'Modular X carriage for TEVO Tarantula by Elzariant' (https://www.thingiverse.com/thing:2034743). My goal was to mount the sensor in such a way that removing the 'Hot End' wouldn't disturb it. Next, I wanted to install a layer cooling fan and duct without disrupting them when swapping out the hot end. The fan duct could likely be improved upon, but it's served me well so far. Lastly, I added the drag chain attachment to the top left hand spacer. All the parts are fully compatible with the original 'Modular X Carriage'. The drag chain is designed by Maxdarkdog (https://www.thingiverse.com/thing:2396718). I forgot to mention the BLTouch offsets that need to be added in Marlin Configuration.h - they're as follows: #define Sensor_LEFT 21 #define Sensor_RIGHT 0 #define Sensor_FRONT 0 #define Sensor_BEHIND 0 The text size is unexpectedly large, I'm not sure why. 24/01/2018: A modified BL-Touch holder was added to provide a greater range of movement and an improved fan duct end that's slightly bent downwards for better clearance around the work piece. 31/01/2018: A mount for a digital dial indicator was installed to assist with bed levelling. The diameter of the dial body is 57mm.
