Tiptanks, nothing wrong with the provided, but I am not good friends with vacuum formed parts with no clear cutting line.
Initial design ok, plan was to include the provided center rib for stability, but I don't think it is needed.
Instead I will make it removeable, mainly for transport but also for easy replacement in case of tarmac scraping.
Currently printing the center section including internal support for matching the wingtip.
I haven't included the front section for green/led light yet, to follow.
Gruss
