About this 3D model

Hello together, i've design an easy to fixed case for the AsRock A3xx Series. With this it is enable to mount an 12,7mm slim DVD drive on it. This is the case i've bought SALCAR Extern Slimline SATA USB3.0 I fixed this case only with three screws, because i had no more. If you like my work, please feel free to give me a tip. Thanks so much René
