This is a simple thing that slips over the end of the upper lever arm of a nail clipper, to give you a better grip. At least for me, it keeps my thumb from sliding down the lever arm, so it is easier to clip my finger nails. I was surprised at how much difference it made..

The OpenSCAD file is entirely parametric, but I think most nail clippers can be accommodated by changing just two input parameters, as explained in the OpenSCAD file.

The sketch (pdf file) shows at least most of the parameters and variables, and a very rough sketch of the thing. It's a scan of the un-cleaned-up sketch I used during the final design stage.


If the print using the included stl file doesn't fit your nail clipper, change the parameters in the OpenSCAD file as needed.

From the OpenSCAD file:

This aid slips over the upper lever arm of a nail clipper to provide a better "grip" than the unmodified smooth metal lever arm does.

The primary input parameters which need to be adjusted for different sizes of nail clippers are: "lcy" and "lcz."

Note that the position of the circular depression, with respect to the end of the nail clipper's lever arm, is determined by the values of the input parameters "lcx" and "b."

If I remember correctly, I printed it with 20 percent fill and one shell, using ABS plastic.

I'm printing this thing next. My fingers are always slipping off that tiny handle.

WOW this is ingenious. Thanks for making this open and not patenting it.
