This is my simple shoe horn design. I wanted something small that I could easily hide in my closet next to my shoes.
NOTE: Before you print it, measure out the width of the back of your foot or the back of your show and then scale the width of the shoe horn to that value. Currently, it is scaled for a MEDIUM-sized foot. If you have a larger or smaller foot, scale accordingly.
I included the 3ds Max file in case you'd like to edit it in any way.
PS. Be sure to check out the new facebook group called "3D Printing Useful Things!" - where you can find lots of other useful 3D prints :)
This can work well with 0% infill and 3 outlines (+3 bottom and top layers), though I like to use 50% infill for added weight. Kind of a waste of plastic bust it feels so much nicer when it's heavier :)
I also sanded mine down with some 400 grit sandpaper to increase the slippery...ness. ENJOY!
