"Look forward mirror" for use following eye surgery (head-down positioning)

thingiverse

This is something that could be very useful for anyone who has undergone eye surgery called vitrectomy, which is done to fix a detached retina or a macular hole. The patient must follow up on the surgery by lying or sitting face down for several days - extremely tedious! A simple variation on a periscope was created to enable a family member to see forward when her head is facing downward - the user looks down into the device and can view the TV, or other people. The user will see everything in its proper orientation - not a reversed or upside-down mirror image. Please note that I did not spend too much time making this look visually appealing, as it was only intended to be used for a few days. Print Settings Printer: G&C CoreXY printer Rafts: No Resolution: Any Infill: About 15% Notes: You can create these parts in any way that suits you best, on any printer with a bed at least 20cm x 20cm, out of any material (I used PLA). I had to print the base diagonally on my printer so that it would fit on the heat bed. Post-Printing Assembly: This originally utilized a 20cm square IKEA mirror with rounded edges (unfortunately no longer available) but any 20cm square mirror would work nicely. This was cut in half to make two identical pieces. Whatever mirror you use, try not to leave dangerously sharp edges or corners that could cut the user. Each piece was glued to the edge pieces using general-purpose glue, backed up with duct tape for security, together with a strip of tape to cover the raw cut edges where the two mirrors meet. This does not look visually appealing, but after all it is only for temporary use! Once the glue has dried, the mirror assembly is mounted using long M3 bolts through the middle holes, with the spacers to make everything fit nicely. If the assembly is too loose or too tight, adjust the thickness of the spacers. A few washers and nuts will make the whole thing secure (I used these knobs for convenience: http://www.thingiverse.com/thing:421801). How to use the mirror: Set the device a little way below the user's eyes, with the open side facing forward. The user should look down at the lower mirror, and swivel the mirror assembly around until he/she can see what they want.
