With this modular wall shelf you can put your things on display in a creative fashion. Print the compartment sizes you need and assemble them in any which way. You can easily extend the shelf with more pieces as needed.

The separate "1x1" piece contains a hole in the back which can be used to mount the entire assembly to a wall. These hole pieces should be attached to at least two other pieces to make sure they hold together tightly.

You can use the customizer to get any size you want. Units are in millimeters. The "width" and "height" values refer to the outside width and height of the part; to get the dimensions of the "usable shelf space", you have to subtract 10mm from these values.

Note that for the "puzzle" to align properly, the pieces cannot be rotated, so you have to choose beforehand which orientation you want the piece to be in.

I also provide a non-parametric version in case you don't want to use the customizer.

Make sure your bed is well leveled; even a slight elephant foot can ruin the fit of the parts.
