Review on Gizmo Dorks 2 85Mm Filament Printers Additive Manufacturing Products in 3D Printing Supplies by Jack Herrera

This yarn is really great. At first glance I thought the thread itself was colorful, but luckily I read other reviews. It changes when exposed to heat. The temperature of the human body is 37 degrees Celsius, and this thread turns yellow already at 31 degrees. I didn't get what that meant when you just hold the 3D printed parts for a while to make them turn yellow (that's really freaking cool). I volunteered for a group that designs and prints prosthetic hands for children. I'm currently working on a hand design and was trying to find a cool print thread. Very smoothly printed, no complaints!
