I found releasing brother Claudio from the sprue to be tricky as one of the mold 'flow paths' was attached to one of his lightning claw claws.

Because the model was at one location attached to the sprue with it's lightning claw, it's very easy to destroy this claw either by clipping or 'twist-turning' the model.

For the rest I haven't seen any problem locations with the sprue, but I'm still releasing the models from the mold.

The models seem to be made in true 40k spirit by the way of the CAD CAM system which is in a sense much like a STC. I'm sure 3D printers were used.
