Optical Tracing Tool

This print creates a reflective tracing tool.  I made it big enough to handle an iPad/Microsoft Surface.  You do need some tinted acrylic, here's what I got:

If you need it to be bigger, you can print an extra section or two and overlap the cross pieces.  However, if a smaller size is ok for your device, it is extremely solid with just two vertical pieces, as this is what I used to take the pictures.  Excellent for anyone learning to draw, as any image or tutorial you can find online can be traced onto paper.  However, my daughter was already in bed, so please excuse my poor attempt at art. She is the artist, not me.
