Made a snow brick maker for my Kids.
Its the perfect sice for children. Not to big but still getting some walls at the end of the day.
It has rounded corners so you can build better curved walls.

Use wax on the inside to get the brick out more easily.

If your snow is very dry (very cold) you need a lot of pressure to get stable bricks!

The trowel is for demolding and clean up at the same time. 

It has a pretty large gap between the brickmaker walls for easy use. 
If you want a smaller gap (which is not needed) you can scale the trowel on plate two, without the buildin supportbar.

I took inspiration form this great model, because it has a good concept (it was to big for my printer and I did´nt want to scale it):
