More #Takai-San pics . Got to rethink the aluminum rods. Way way too much flex and instability.
Cross-bracing those would do wonders to the rigidity
@Griffin_Paquette can’t cross-brace delta rods 
I use ‘Sturdy Stakes’ from Lowes or Home Depot, but I suspect that I did not cut them all the same length and my 3D printed rod ends have needed replaced a number of times so that does not help either.
@NathanielStenzel thanks for the tip
@kenneth_rooks https://www.thingiverse.com/thing:334094 that is a link with more details and the rod end design. I have considered drilling a hole in the sturdy stake and rod end to fasten them in with a screw. I think that may make it easier to swap them out. If you use something else than the rod ends, this link will at least give more details on measuerments and preparation. Good luck!
Wow, thanks you the info!
