In design, one usually thinks of having a master plan then translating it to reality. In this design process - I started with one connector that was 3d printed, wood planks and L brackets. I mounted one wood plank to the wall with a L bracket then added a connector and added more until it looked interesting. After my form was created I made use of the shelf by filling it with my items. This bookshelf design was made my doing with no initial masterplan.
