A simple and sturdy shelf hook for the popular Ikea Lack floating shelf. It's not a pretty design but very functional and robust, will make a few variations of this and upload when I have time.
Check my 2nd version of this out here http://www.thingiverse.com/thing:1131970
As can be seen in the image it can support 2 earphones quite easily which suits me, appreciate this is not every ones requirements. The lack shelf is 50mm thick as standard, I made this dimension on the bracket 50.5mm to allow for any tolerance issues.
The final print shown was printed in PLA, 300 micron layer height, 15% infill, 2 shells.
**Update reorientated STL files view and added a second version with curved front.
