This is a Time and Relative Dimension in Space. A time machine and spacecraft in the British science fiction television program Doctor Who.

I've adjusted the model (the Tardis2 model) for more authentic 2x3 windows. It's also now using the window color for the lamp on the top.

Time travel is guaranteed! By scaling the model up 2x you will travel about 4.5 hours into the future. Trust me.

I made the shape in TinkerCad from little blocks and holes. It's an eyeballed design from a Dr Who necklace I have. The biggest challenge was figuring out how to separate the blue and white parts and then join them back together in a print.

It generally works without raft or supports. Make yourself a dual print by combining the body and the windows STLs.
