This is a kayak fishing tackle box adaptation of the Gridfinity rugged cases. My adaptation allows you to stack and latch them together modularly while still opening them when needed. There is also a mounting plate for kayak t track. This gives you a great way to store your tackle exactly where you want it!

It uses the Gridfinity standard of 5 bins wide, 4 bins wide and 6u tall. This makes the box similar in size to half of plano 3700. However, you can print your own bin sizes and easily go two level in each box. This is fully customizable modular tackle storage for how you see fit.

You will need:

12       30mm M3 screws (button head work well) per Fishfinity box. 

 2        30 mm M3 screws per base and t slot bolts. 

2         ¼ 20 t slot bolts.

I used these great printed knobs for the t slot bolts:

I also highly recommend these bins:
