I designed this 3" long trout to give out at fly fishing events when I demo 3D printing. But why should I have all the fun! Print your own with this free STL file. Use them for key chains, Christmas Tree ornaments or just to play with. Make a rainbow of trout! I suppose you could attach some hooks and use them as lures too.

Printing Tips

You can print these solid but to get the open effect like the trout in the photo, set the top and bottom layer thickness in your slicing software to "0". For KISSlicer, this is called "Skin Thickness". Then, pick an interesting infill pattern. 20% to 40% looks best. I use 4 perimeters to make sure the profile is strong.
