Description
A fish scaler using three bottle caps. I used a version of this with bottle caps screwed to a piece of wood that worked great so thought I'd make something a little more ergonomic. I use super glue to bond the caps in place and it works great. Alternatively, I provided a pilot hole to screw each cap to the handle so you'll need to drill a corresponding hole in the cap if you want to try this.
I printed this with 10% gyroid infill except for the area around the three pilot holes. I used a PrusaSlicer modifier to print solid cylinders to reinforce the pilot holes for screw mounting the caps (see images).
