This is a small add-on for Matthew Ghost’s model “Skadis Modular Storage Organizer | Storage Box.” It’s meant for anyone using the organizer as a tower on a desk or shelf (so, off an IKEA Skadis board). When mounted on Skadis, the board helps keep the build stable. Off-board, stacked tiers can rotate slightly around the Pivot, especially as the tower gets taller. This clip removes that play by locking two stacked tiers together.
