FT Pontoon for FT Sea Otter.
thingiverse
Update: I love the look, but think they're way too small for the Otter in the end - need to be bumped up at least 150%. Scaling up will mess with the size of the connecting area. Getting an idea about using a new bracket style connector to make them a stronger part of the wing. Watch this space for V2. Very much under construction and first pontoon design test.
