Here's a simple and direct tool for crafters of jewelery or miniatures to use :)

These frames, unlike the most common used side guides, don't move around and allow to stretch your clay in both directions, without a need to move the guides! 

Featuring the text for the sizes in hole format, you won't waste time nor filament changing color to make text visible! 

In the file there's 1mm, 2mm 3mm and 5mm! Let me know if you would like to see other sizes too
