For those who love dragons AND legos comes this little hybrid number: The wings from hydra attached to the connectors of lego! solid layers for the wings- I did loose honeycomb and it still worked. PLA will be better suited though, with a more solid composition. update: made the interiors solid (that can only help) and cleaned things up a bit cosmetically...PLA yielding solid lego compatibility on the upper 2 connectors, trim a bit on the side connectors to make them work or consider support material...
