Sorry for that, it did work for my drone flawlessly.

ok c’est alors peut être un problème de paramèttage ou autre.

Okay, then it's possibly a settings problem or something else

pas mal du tout mais j’ai dut imprimer deux fois et les deux on foiré. 
un peut déçut car j’en avais besoin.

not bad at all but I had to print it twice and both attempts failed I am a bit disappointed because I needed it

<p>I lost 2 prop guards of this cheap, but surprisingly good drone. So I desgned and printed spare ones.</p>
