I purchased a clone MOC out of interest a few months back, this following set.
Because it does use clone pieces, I knew there was a high chance of breakage and poor fit, especially in the tensegrity arm actually supporting the upper structure. The arm failed today, so my plan is to replace and reinforce the original arms with official Technic parts.
My plan is to use the 5x3 L beams from Technic to alleviate the strain on the angled portion of the liftarm, which is taking a lot of weight. The arm, removed from the set, currently is bowed in due to the strain.
Because the snaps happened on the outside corner, I was wondering if attaching L beams on the outside or inside corners would be sufficient, or if there is another method of reinforcing this liftarm so that the stress in that region is reduced.
Adding the L beams in parallel with the liftarm would distribute tension to the L beams rather than just the angled bit, which should reduce the stress.
Alternatively, adding them underneath would (hopefully) add compression on the L beams in the opposite direction.
I believe that the official technic pieces should be a bit stronger on the replacement liftarms, but I'd like to reduce the strain in this area anyways, so alternative solutions are also welcome.
