Spreader Arms for Kossel Wire Braces 2020 (Fix Volume Loss)

Spreader arms for my Kossel wire/cable frame brace kit here: https://www.thingiverse.com/thing:2941886

The original brace kit does wonders for frame rigidity, but comes at the price of some of the printable volume. I racked my brain for a good, long-lasting way to update the braces to move the wires out, then realized there was a simpler way. These spreaders push out the wires to reclaim most* of the lost volume.

(* Specifically, I'd guesstimate these reclaim between 50 and 60% of the loss, but they reclaim almost all of it down low, so nice for printing long stuff -- just gradually less as the height increases and the wires slope back inward. I didn't want to push the arm spread tooooo wide until I could get some good testing on the 100mm version, but assuming they don't have any breakage issues, I may publish, say, a 140mm version that would get back more.)

Print 3 of these.
