My school uniforms are strange. Their buttons brake into pieces suddenly. Are my uniforms tight? No. So, I suspected the buttons, not my belly. I 3D printed buttons using @proto_pasta carbon fiber filament, and problem got solved. I actually 3D printed a lot of them, and gave some to the people in my club in school, MakerClub.

I 3D designed it using @SolidWorks. I 3d printed it using @makerbot .
