BMCU 370X PTFE Tube Brace

A brace to reduce binding of the PTFE tubes of the BMCU between the BMCU and the tool head, when mounted vertically.  The lateral strain was causing the buffers to bind and rub heavily. The brace removes the strain by keeping a length of straight PTFE tube just forward of the buffer to assist with consistent alignment of the buffer during movement. 

This was modeled for the version here:
