Thước Tìm Tâm Mini - Chỉ 6g

I wanted to make a small, handy center finder for rods and other small objects like wooden wheels. It covers diameters from 10–80 mm.

The center ruler is offset by 0.25 mm to account for pen thickness, which I find very helpful and often miss in other designs.

The tool weighs only 6 g and prints in less than 15 minutes.

You can mirror the model in your slicer depending on which hand you write with.
