MMU2S PTFE Tube Stabilizer/Tensioner

I did not create this; I've posted it here in the hopes that it can be helpful to a wider audience. It is currently found on a company website reachable only by direct URL.  Below are the author's notes from that page. 

Notes:

o   Stabilizes the tubes by keeping them evenly separated and snug.

o   Because the tubes in the pathway are now all wider the filament sits “looser” (is that a word??) in the tubes and the filament sometimes had a tendency to fall out of the tubes when it was retracted (and especially if using an auto-rewind spooler since that yanks a little), so I designed this piece with a radius that allows just enough tension to prevent the filament from falling out, yet still does not impede smooth movement.

o   The “pigtails” slide all the way into this stabilizer/tensioner.  I orient this so the holes you put the filament in are pointing up – in other words, the side that has “MMU2S” printed on it should be on the left side of the printer (left if you are facing the printer).  

o   I did not measure the tube lengths, but I made them long enough to slide all the way into the stabilizer/tensioner and then about 20mm of extra for a gap between it and the compression connectors.

o   The STL is not oriented right for printing – print on its side with the part that says “MMU2S” up (no supports should be needed).  I used 0.2mm layers.

o   The tubes slip in the end that says “MMU2S” (the other end has a lip to keep them from coming out so don’t try to insert from that end).

o   When inserting the tubes be gentle so as to not crinkle them, especially since the sidewalls of the 3mm ID tubing are thin/weak.

o   I created this in Fusion 360.
