The Prym Vario pliers are a tool that allows you to press a variety of buttons, rivets and the like into fabric. Prym supplies you with standard pliers - and then only adds small plastic parts to adapt to the specific part. (See: https://www.prym.com/en/how-does-the-vario-pliers-work )
The plastic interface parts are friction-fit into plastic insets in the pliers. At some point one of those got lost or broke (that detail is lost to time…). So, since we did not want to replace the pliers we designed a replacement 😀
This inset can easily be printed and used to replace the original one.

(Since Prym is probably mostly sold in Germany, let's add the German name: Prym Vario Zange, Vario Inlays für Vario-Zange)
