Scotty rod holder base adapter for kayak track
A plate that lets a Scotty 241 or 244 round deck mount, and therefore any Scotty rod holder, bolt onto the 25 mm gear track found on Oru Kayak, Perception, Old Town and Wilderness Systems boats without drilling the hull. The plate is 60 x 110 mm and 8 mm thick, with two 6.5 mm slots for 1/4-20 track T-bolts and four holes matching the Scotty base pattern, plus a 3 mm perimeter rib underneath so it does not flex when a rod loads the holder. Print it flat in PETG or ASA at 50 percent infill for UV and salt water resistance.
Track spacing and hull curvature vary between kayaks, so a fixed downloaded plate rarely sits flat. In SpeakCAD you give your track width, bolt spacing and the base's hole pattern, preview the adapter free in the browser, adjust the slot length in the chat, then download the STL.
Create a kayak track adapter plate 60 x 110 mm and 8 mm thick with two 6.5 x 30 mm slots for 1/4-20 T-bolts on the long axis, four 6 mm holes on a 50 mm square for a Scotty round base, and a 3 mm perimeter rib underneath.
