Corner mirror stick
thingiverse
To see around corners, check out the latest development versions on Github's o-jasper/various-physibles repository. Follow these instructions: print one stick and three corners; clean any plastic debris from where the glass goes, especially near the stick-adorned corner; ensure clear holes in bulbous parts for easy wire insertion; attach corners to the mirror carefully without breaking it or hurting yourself; use wire (steel preferred, but nylon kite wire is an option) to assemble the device, avoiding force when placing corners on the mirror.
