Mirror Upright

thingiverse

I often find myself wanting to glimpse what's printing on the other side. In search of an affordable solution, I stumbled upon a great mirror for $10.40 that measures 8.5x11 inches, available at Amazon. The only catch with this particular mirror is its design: it's intended for use at an angle, allowing you to see your face from a desk or table. However, by placing the mirror upright behind my 3D printer, I can now see the back of the part as it prints.
