See the Cyber Shelf!
Can be used with or without LED lighting. I personally used a small battery powered LED strip, but I think a small RGB bulb would provide more even lighting.
The shelf is held to the wall using two #6-8 screws & anchors. Mounting distance between the two screws is 130 mm.
This is a decent sized print, coming in at roughly 250 x 134 x 160 high (mm). I used 40% infill (in retrospect I feel like this was overkill). Print time was approximately 36.5 hours.
Support material required is minimal, I only needed a little bit inside the screw mounting pockets.
Thanks for viewing,
