Trinus Cable Relief

I've got a Kodama Trinus printer -- and it's great, but needs a little help in a few places. In particular, the print head cabling desperately needs some stress relief near the processor board. I printed another cable support design on Thingiverse (Afro3dPrinter's design https://www.thingiverse.com/thing:2072628), but it just wasn't stiff enough for my taste -- so here's my considerably beefier take on things.

This design is *just* short enough to print on a Trinus, if you orient it diagonally on the print bed.

Features in work:
1) This design includes two holes so you could zip-tie the cabling to it -- but I'm not sure yet that they're really necessary.
2) I've now beveled the edges of the semi-cylinder that hold th
