Divider for IKEA Vattenkar shelf

Shelf divider for IKEA Vattenkar desktop shelf. Uses 3x 6mmx3mm circular neodymium magnets to stay securely in place while still allowing you to slide it around when necessary.

Print with zero top and bottom layers, increase infill percentage, use honeycomb infill, and increase perimeter count to save filament. I used slip joint pliers to press the magnets in, the tolerances are pretty tight so you might not be able to do it by hand.
