Seam Guide Ruler (mm) - Sewing Machine

The seam guide ruler has a set of holes to easily measure the distance between the needle and the edge guide. Just lower the needle into the correct distance hole and place the edge guide on the machine. 

Use two 10x3mm magnets like this one here https://geni.us/Magnets10x3. This allows the edge guide to stick to the feed plate on most sewing machines.

Printed with 12% infill, 0.4mm nozzle, 0.2mm layers in PLA. Use the 'Fill' tool to colour the text a contrasting colour.
