SUP board fin adapter

This model is a 3D-printed fin adapter designed for stand-up paddle boards where the fin box has been glued slightly off-center. In my case, the original fin box was installed about 3 degrees to the left of the board’s centerline, which caused the board to track unevenly. Instead of removing and re-gluing the fin box, I created this adapter to correct the alignment. The adapter adds a built-in 3° correction to the right (from paddler perspective) so that when the fin is installed, it sits straight relative to the board. This restores proper handling and tracking on the water. Material recommendations: PLA is fine for light use or freshwater paddling.PETG or similar materials are recommended if you want better durability, especially for frequent or saltwater use. Customization:The current STL file is set for a 3° correction. If your fin box misalignment is different, you can easily modify the angle in the STL file to suit your board.Happy paddling!
