Vegvisir - gift for my dad

My dad's birthday is coming up and both mom and dad are into Vikings. Perfect to give away a 3D printed Vegvisir coaster for dad so he can start off his morning coffee with style and luck:) 

A vegvísir (Icelandic for 'sign post', Wayfinder) is an Icelandic magical sigil intended to help the bearer find their way through rough weather.
