Shelf support low profile - 70mm

Shelf support for 200x18mm wodden boards - 70mm

I needed to add some wood shelves on my desk, resting on top of it, so I designed this support. 
 

This is low profile (70mm) an it's complementary to the other support I have made:

It's designed to fit standard wood boards 18mm thick and 200mm depth; the lenght of the wood board can be any. They are very common melamine boards, very easy to find in stores like Leroy Merlin or BricoCenter, typically  600mm, 1000mm or 2000mm long.

The space below the shelf is 70mm and they can be stacked.

They can be put side by side to extend the shelf in lenght. Supports are large 30mm, it's enough to receive two boards side by side without losing stability.

Printed in PLA with 15% infill, they are pretty stable.
