This is a second design for a toothbrush holder, but the design is generic enough I figured I should advertise it as a small shelf. The back side has a flat panel that you can use to apply mounting tape, so you can hang this on a wall. On the right you can see the completed shelf.
I had some trouble with the pocket location getting altered during the cut so I opened up the holes (not using the laser). The model seems sound, so the problem must have come about elsewhere.
