Remix of this great design to be able to use IKEA FIXA wood screw sets that many have available to mount the sheet holder directly to a wall, shelf, without having to use a bunch of M3/M2 screws.

Makes it harder to mount, but easier to source the hardware (that many have available anyways).

Use the 4mm screws from the FIXA set to mount a set of three drawers on top of each other like shown in the pictures.
