thermochromatic - not thermostatic

Thermostatic - stays still when warm :-)

Yeah it's fun stuff, works great for coasters and jewellery.

But given that the birdhouse would be outside, in the uk I doubt it'd ever change colour apart from in summer.

Cool looking birdhouse.

But seven hours ?
Looking at the design looks like it should print with 3 layers and no infill in a lot less than 7 hours.
But can't be arsed to join yet another website just to download it :-)
