About this 3D model

I couldn't really find any dice I liked so I have spent the whole weekend designing some and after like fifty or so different variations I ended up with these four that I really like and hope some of you might like them too. I really took my time with it and even checked that they are balanced to the centre I designed them with 3d printing in mind so you can print them all without supports and can achieve a great finish with minimum effort and they are all oriented in optimal printing position.
