This is a remix adjusted for using the 80x70x40mm mirrors from AliExpress

Mirrors

Printing instructions

You can either use the pre-sliced .gcode files (for Prusa MK3/S/S+):

• 6x mirror123_0.15mm_PLA.gcode
• 1x center_0.15mm_PLA.gcode

or slice and print the STL files on your own (I highly recommend enabling the ironing feature in the PrusaSlicer to get a nice flat surface):

• 6x mirror_1.stl
• 6x mirror_2.stl
• 6x mirror_3.stl
• 1x center.stl

The total printing time is around 33 hours.

Assembly instructions

• Upside down, put together the inner loop (1-1-1-1-1-1)
• Upside down, put together the outer loop (3-2-3-2-3-2-3-2-3-2-3-2)
• Place the inner loop on the outer loop, and use a rubber mallet if needed
• Place the centerpiece in the middle and use a rubber mallet if needed

Installing mirrors

• Remove the back protective layer from the mirrors
• Peel off just a little bit of the front protective layer
• Install mirrors inside the frame (don't touch the uncovered parts to avoid nasty fingerprints)
• Remove the rest of the front protective layer
