Fencing Foil Grip

thingiverse

I have a pair of fencing foils that are badly in need of new grips, so I've decided to design a replacement right away. I'm not ready to print them yet, but maybe someone will find this useful someday. The measurements aren't perfect, but I think the shape looks about right now. The preview from the .scad file is really misleading, despite my best efforts to fix it, so I've included an .stl file as well. Updates I improved the .scad a lot. I originally designed the main part of the grip by stacking up ellipses and trying to loft them with hull(), but OpenSCAD can't do that trick. Since hull() only works on 3D objects or on 2D objects in the same plane, they had to be turned into cylinders first, but their height made the result look off slightly. The fix was a bit of a hack, so I've now replaced them with spheres, which work much better. I've also left the rounded top and bottom because I don't think they'll get in the way, and they look nice too. Also some improved measurements. Still haven't printed these yet. And finally, I figured out what was wrong with the display. I used a diameter instead of a radius, and for some reason it looked okay in my old version of OpenSCAD, but now that's fixed.
