About this 3D model

I wanted to build a cool Batrang "Fridge Magnet" that looked like it had been thrown and stuck into the wall, it needed a little sanding but I think that is more to do with the filament I was using than the model. I bought 4mm x 5mm Neodymium magnets off Ebay for this and used 3 in each Barring for a nice solid feel. Hope you enjoy, this is my first upload so any advice is welcome
