The original model by @asquared is awesome and the clip fits perfectly in the Yetis, but we have a Moosejaw 50qt on the flats boat and needed more rod storage! So I modeled a clip to fit the Moosejaw, as it's significantly different. You'll need whatever mount you want to use (I highly recommend the model this was remixed from), two M4x12 (or M4x15) bolts and two M4 nuts. The spacing between the bolt holes is 30mm centered.
Edited and reuploaded for more stability!
The author remixed this model.
Clip to fit Moosejaw 50qt cooler as opposed to Yeti cooler as the side clip is wildly different.
