TBS Source One V5 Wire Protectors

Yep, it's a blatant rip off of the plastic protectors that come with the Apex.  But they're pretty awesome and the whole frame's a rip off so why not.

You can print them laying down if you want, but you will need supports.  I printed all four at once standing vertically and was happy with the results.  It takes a bit longer but the results are nice.

I sized all the walls at 1mm, so you should print it with a .50 extrusion width.
