Collapsible Altoids 3D Viewer

**REMEMBER!** You need CONVEX LENSES for this to work! If the image you see is blurry or not right, adjust the model by shortening the arms! If you lengthen them, that's fine, but if they're too long it won't fit in the tin anymore. The lenses I used had a focal point of about 12cm. (look through the lens while holding it 12cm up. Is the image clear? If not, you need a different lens or different arm lengths.)

**NEW!** Modified design for lenses with a 5-6cm (2-2.5 inch)
