Makerbot tube support

thingiverse

This modification addresses an issue on our Makerbot Dual (CTC) when occasionally the filament would break where it meets the feed block due to the continuous movement of the ptfe tubes as the head moves during printing. It provides support for both the PTFE tubes and the cable loom. The bracket fits in place of the spacer on the rear screw that holds the top plate of the print heads securely in position.
