What the self includes :
the shelf's body :
there are pieces with one, two or zero screw holes. you can mix and match them to customize your shelf. there are also half length pieces for further customization.
the end pieces :
there is only one design for the end piece. it needs to be glued on either side of the shelf.
wall mounts :
if you'd prefer to hang the self using the wall mounts you can choose to print it using the zero holes pieces.
if you prefer to hang the shelf from above you can ignore the wall mounts.

Printing the shelf :

still testing

shelf was successfully printed with
4mm nozzle
PLA
205 nozzle temp
55 bed temp
4mm layer height
80 mm/s speed
15% infill
use supports for the railing only
end pieces and mounts can be printed laying flat to avoid supports
 

Assembling the shelf :
print as many body pieces as you want for the length of the shelf. you need to have either at least two screw holes in the body pieces or to print the wall mount pieces.
glue the body pieces together. at either side of the shelf glue the end pieces. glue the wall mounts if necessary.

Hanging the self :
shelf can be hanged with screws from above the shelf or screwing the wall mount attachment. command strips can also be used to either glue the back of the self or only the wall mount pieces without screw holes.

What can the shelf hold :
do not place heavy objects on the shelf. it is mostly a decorative piece. i designed it to hold nail polish specifically, so keep that in mind.
