This is a wall mount for Ikea AULI mirror.

I had a package of AULI mirror panles lying around so I designed a wall mount to hang them on top of each other. I think this would work for any square mirror panels that are <4mm thick.

I printed in transparent PETG, but I think PLA would work as well. 

Printed with 0.2 Layer height and 15% infill (I would recommend to up this a little bit).

Mounting guide:

1. Print the Bottom Mount and try to get this as leveled as possible. I used a bit of masking tape to mark the holes after putting the mounts on the mirror. Then mark this on the wall.
2. After securing the bottom mounts to the wall. Put in the bottom mirror, put the middle mount in and mark the drill holes for the second mirror (above the lower mirror). As the bottom mirror is held up by the bottom screws, the second one is held up by the middle screws.
3. After securing the middle mount to the wall, use a pen to draw the corners of the mirror to the wall, as this is where we put the top fasteners.
4. A tip, that I had as an actual shower thought after mounting the top mounts myself, is to flip them over, and align them with the corners we drew, then mark the screw hole. This allows the top fasteners to be in the exact correct spot.
5. Screw in the top fasteners, and then slide the top mount on.
6. Done!
