I have for the first time just tried my hand at aluminium casting using greensand. I ended up with a brick of aluminium as the mold split due to the heat...

At least I have a cool paperweight. ?

This is the safety flap for a biltong cutter I have designed and want to produce. It is called the Carnivore Cutter and has a lion paw print in the design.

On the right is the 3D printed version of the flap.

Any tips or advice would be appreciated. ?
