Just got a new Knarr and there is a seeming lack of any sort of guidance or custom built adapters to mount transducers cleanly. I have a 3D printer and took about a week of tinker(CAD)ing around before I felt good publishing my design. This is specifically for a Garmin GT20 transducer and a 2025 Jackson Knarr, it's super firm, clean, flat, and no wobble.
I'll publish this for anyone to use for free on makerworld soon but wanted to share here and see if anyone had a similar experience and if I should take this custom transducer/kayak idea forward.
