Skadis top shelf bracket to mount a shelf/board on top of the skadis board. 
No gap towards the wall. Maximizes usable surface on top.
The bracket fits perfect with a 12cm deep board (8mm high). Narrower boards works of course as well.

The prints you see on the pictures were printed with 0.2mm layer height. Smaller layer heights would probably improve the quality of some areas a bit more (also the filament I used probably wasn't dried in over 2 years :D)

Feel free to let me know what to improve.
