Case for smallest toy drone Proto X or Hubsan nano

This is a gift for my friend Minch. i send him a world smallest drone called protox. but i find it is hard take , easy broken it is so weak~and cute~ so i decided to make a case for it~
first design: thin insider cover ,higher box ~ but while i was going to finish my printing , it went wrong.i had to stop the printer, so the gray case didn't finish printing.. but i don't want to let it waste. so i designed the second cover for the broken case..
design 2: lower gray case , thicker taller outs
