3d printed parts durability in kayaking

[SoCalEDC]

A few months back I remember someone talking about 3D printing mounting plates and covers for transducers.

I am curious as to how they hold up in the conditions we put them through, and what kind of filament they were printed with.

I have been trying to find a way to mount a larger fish finder (7") on a stealth kayak hatch lid. I modelled a bracket that will interface with the existing mount and keep the sounder closer to the deck (the factory mount is pretty big relative to what I want), but I have my concerns about PLA and the sun/salt/weight of the head unit and force it will be under when the kayak is in rough swell and that head unit is putting force on the tabs back and forth and side to side as the boat rocks.

I am trying to avoid using metal (stainless or aluminum).

Thanks.
