Penholder "Dwarven Hammer"

I made this model of a penholder for my Wacom pen, formed like a Dwarven hammer smashed into the ground. But when I checked online how much it would cost to 3D print it, I decided that over 400€ is too much for a penholder! ;)
Its real-world scale is about 15x15x15cm³. So instead of actually printing it I decided to showcase it here since it was a fun experience to create it.
