Key cover hearts (remix)
This is a remix of light974's key cover. Credit goes out to him/her in the 1st place. I just added an image.

Use this model for your round keys, paint it if you don't want to use different materials. The model light974 has uploaded has a scad file; this way you can adjust the size of the key cover. I'm not able to make a scad file. So this is a one-size file. But you can tweak around with the dimensions in several programs. Some are 123D design (free) and meshmixer (free). If you download these kind of programs, you can easily adjust the x,y,z size to match your (round-)key.
I have printed this model in white Ultimaker PLA with an 0.4mm nozzle at 0.1mm layer height. I used 20% infill. I did use a brim. I placed the model on my platform with the
with the curve at the top (just the way it appears in your slicer).
I used this video for making a 2d picture into a 3d model:

What did i do?
I picked a logo from my browser and have put it in svg format in inktscape. Opened the svg file in blender and made it a 3D object. In meshmixer i have repaired the file; and erased some aspects. Than i have merged the key cover with the image after scaling the picture. Saved it as a STL file and sliced it for printing. Cause the model has still some issues even after repairing it in meshmixer; i have decided to export it into Netfabb Online Service. This is an app i discovered recently after using MakePrintable. Cause MakePrintable in my opion only gives us 3 procedures of fixing an STL file and, with Netfabb Online Service the frequency of STL fix procedures is unlimited, my choice was clear. It worked well for me and i could slice the model without any problems.
