I needed a backrest table for my sofa, but wasn't happy with the options available. So I made my own backrest table by creating a suitable bracket.

The hardware store had wooden fence pickets (150 mm width) on offer, €3.50 each. So I printed 3 brackets from PLA and screwed them on the picket, using 3 x 20 mm screws. 

Recommendation: If you're using a power drill, don't go too high with the torque. Go nice and slow ;-).

Print settings:
 

• PLA (I used Spectrum Ivory Beige)
• 15 - 25 % infill

For the future, I'm planning to add either Multiboard or Gridfinity elements to the picket to make it even more functional and stable.
