One-Arm Fisherman

thingiverse

This is a custom ice fishing rig to automatically set a hook on a bite; similar devices exist elsewhere in the world but this was simplified to be inexpensive and built with my local parts. The 3d printed parts create the action for the device, using the spring energy available in the rod. This will require tying a small loop around the tip of an ice fishing rod so it can be slipped around the finger in the middle of the assembly. The body of the device can be made of wood. It was designed for 1x1 nailing strip which works out to 19mm. I've been told this is the same dimensions as 3/4" square aluminum tube if you want to make the thing stronger. I found that the ideal lengths of wood are 6" to 9" for the legs, and 24" to 28" for the center body. The Rod holder has multiple screw holes in the bottom so the shaft can be extended/shortened a few inches which you can base on your own rod. The models were designed around, and uses: 5 x 3/4" #8 Wood Screws 5 x M6 x 30 Machine Screws 5 x M6 Nuts 1 x 1x1x48 Nailing Strip If you try 3/4" aluminum tube I'd love to know how it fits. I've included a part called "testsquare" which is the same dimensions used for where the wood is inserted. Print it off, scale it until it fits the aluminum tube, then print your parts at that scale. It should be close enough to not change the hex holes built into the part and the same metal parts should work.
