3.5" light to medium duty mini rail mount base for kayak or boat. Suitable for mounting one Scotty, YakAttack, Railblaza, or similar track adapter, for a rod holder, GoPro camera mount, stern light, or my bow light kit. An optional backer plate is also included, if needed for mounting on thinner materials, like a plastic hatch cover. This part is NOT recommended for heavy duty applications, like downriggers or large salt water rod holders.

For a camera mount, you may want to consider these parts to finish the project:

To start: https://www.amazon.com/Scotty-438-Gear-Track-Adapter/dp/B009JAZW6O
Then: https://smile.amazon.com/Scotty-Portable-Camera-Compass-Mount/dp/B0060UH3M2. I have both of the above that I use for various purposes on my yak.

And to top it off for GoPro camera: https://www.thingiverse.com/thing:2763695

There may be Scotty or other "track mount" arms and mounts for cameras, but hard to recommend something not knowing what camera or how intend to mount it.

The above settings produces nice clean results on my printer, but yours may be different since PETG can be a finicky material. PLA+ may be an acceptable material for light duty applications. PLA is NOT recommended. I am working on dialing in ASA, but not there yet. Will update for ASA settings when available.

For thicker material and light duty accessories: 4 stainless steel M5 countersunk screws or well nuts.
For thinner materials or medium duty accessories, like rod holders, 4 stainless steel M5 countersunk bolts plus the optional backer, with M5 washers and nuts on backer side.
