TARDIS belt buckle

I broke my coat's belt buckle, and for the 50th birthday of Doctor who, as a fan, I couldn't make a other design ;)
Enjoy !

I printed this in PLA (a glow in the dark chinese bad one, 'cos I had no other blue :( ) but it's still pretty cool.
( 3 shells, 40% unfill to be sure it will be strong enough, but less could be ok ;) )

It's too high sized, don't hesitate to change the Z size.
