No secondary optimization whatsoever, but wanted to do justice to SpiritualShampoo's original puzzle and complete it in 3I. The hardest of all the non-triplex bonds to get rid of are the three atoms at the tips. Tried to find some clever rearrangement by splitting off different chunks of the molecule at a time, but that didn't pan out, and instead went for the most direct approach of getting the three atoms debonded together and then reattaching them one at a time. The rest is getting the right bonds on the seven central atoms, which is conceptually straightforward, but sorting out the bonder fields was ironically even more frustrating than handling the tips.
