This is a remix of a origami tortoise from thingiverse to add a triangle with a hole at the top of the shell so it can be hung as an ornament or any other application. The top shell slides on the bottom of the model. This can be a slightly tight fit, so you may want so scale up 1% if you don't want to push the model together with force and to stay interlocked. This model prints without the need for any supports. Fusion 360 was used to remix the model.
