Fish Stringer Sheath

thingiverse

I've made a couple of fish stringing needles from a round stainless steel bar that I cut from some kitchen tongs I found in a local store - the largest diameter I could find was 5.7mm, which seems to be similar to what commercial products use. The overall length of the needle is 150mm. It has 4x 4mm general purpose holes for attaching it to a buoy or anything else. It can be attached to a diving belt - the hole is for 50mm belt, but can be changed in the *.scad file for different sizes. I've got some 180kg monofilament for real life use. Printer: HicTop Prusa I3 ABL Print Settings: Rafts: No Supports: Doesn't Matter Resolution: 0.2 Infill: 80% Tetrahedral I printed this with supports, but I'm quite confident that it would be fine even without - the gap is around 60mm which should be easy enough to bridge. Printed in ABS as the design is based around its flexibility. Post-Printing: I just removed the supports and brim and sanded smooth. How I Designed This: It's designed around the specific sizes of material I have. The *.scad file is attached and I've tried to put enough comments to be easy to change the needle size and diameter for it to generate a suitable sheath for different sizes - it's parametric so inputting the diameter and length should be all that's necessary to do, I've tested it for diameters 6.2mm and 10mm and both outputs are acceptable.
