I thought about that, but mine never rubs the edge because I have the case on all the time, it's just rubbing on the belt that bothered me because it pushes it pretty good sometimes.

That's what happens to me..  Enough to twist the belt 45 degrees.. 

I just finished soldering in pin headers for gcode fan (next project), and while at it, a USB +5V on/off switch (to switch into 'Programming mode',  after cutting the trace previously).

Now that it's reassembled, I think this will make a (useful) test print! 

Mine never really hit the frame edge, even in the summer when I printed without the case all the time.  Just kinks down by the belt naturally for mine anyway.  Now with the cover on, it keeps it away from the top edge anyway even if it wanted to go there.

You might consider adding a small lip to cover the metal edge to protect the bundle.

its right here...http://www.soliforum.com/post/6874/#p6874

if you have the lip you don't need the magnets but you raise the cover slightly...its all about trade-offs.

Thanks to all three of you guys-  this looks quite elegant.
Have you had any shifting with magnetic adhesion or does the cable assy slide up easily?

It will likely be my next mod print, prior to gcode fan

2 STL's which have different origins if you want to print laying down or standing up.  I printed standing up because I didn't realize it would print laying down until after I started the print.
