Thước đa năng 120mm (120mm Multi Ruler)

120mm ruler with 1 to 10 mm hole gauges, hex holes, slits and arc templates.

Should be printed with with a relatively small nozzle (0.4mm or lower) and a color change after the 1.2mm layer for best results.

Depending on the precision of your printer, you may want to drill out the holes with their corresponding drill bit for the best result, as well as force hex keys through the hex slots.
