The guy who runs http://TriDPrinting.com (delta parts sales site) originally came up with this frame+mechanism, which he called a “flying skydelta.” Daren made some nice improvements in his build.

There’s really three interesting things to this printer design:

  1. Octahedron frame. Super stiff at very low cost.
  2. Spectra line tripod design. Very cheap to build. Daren’s use of linear rods as a triple spool for each drivetrain is simple and clever.
  3. “Super gravity pole” – the spectra lines are preloaded by a tensegrity style structure so the end-effector is much more stable than a purely gravity-loaded end-effector (like in the Hangprinter). Each drivetrain directly pulls on the end-effector like a Delta, and pushes down on the end-effector through the super gravity pole.

@Ryan_Carlyle Thanks for the information. I had no idea that a similar design existed.

@Matthew_Del_Rosso Why spam?

@Arcus_3D ​ the comment is invisable to me as I marked it as spam, and bc I my initial comment was 3w ago, I have no idea what it said, so I cant explain my action

Thank you @Daniel_Kruger . Daniel was kind enough to attempt to keep me sane during #MWRRF while showing off the previous printer with serious sleep deprivation.
