Wanted to add some rod holders to my Jon Boat and made this to fit in the commonly used track system on most aluminum jon boats.

I have tested these on the following brands with success, YMMV. - Grizzly, Lowe, G3 Boats, Tracker, Lund, SeaArk and Xpress.

PETG

25% Infill

Parts needed PER ROD HOLDER

Qty 1 - Stainless 1/4 - 20 x 1.25" Bolt (may vary by boat manufacturer)

Qty 1 - Stainless 14 - 20 T-Nut

1/2" Drill Bit to Drill Hole into Rod Holder

1/4" Drill Bit to Drill Hole into Rod Holder

Large Drill Bit is so you can feed the screw into rod holder

Smaller hole is for screw to pass through rod holded into 3D printed part.

Here is a link to the exact rod holder that I used, but they are generally a similar diameter so other models should work as well.
