General info

Small tool to avoid pressing keys on a PIN terminal in the supermarket.

Alternatives

Can be worn as shown on the picture, but can also be turned 180 degrees, thus protecting the tip of your finger.

Print a second one for your thumb and use it as a pinch, if wanted. Or print one for each finger.

How to create one

Measure the diameter of the second bone in your finger. Replace that in the SCAD file (needs openScad to generate new STL)
The sample provided is measured on my finger (20mm) and is 35mm long.
