Equal Spacing Marking Gauge

thingiverse

This is a marking gauge for making equally-spaced marks at any distance between about 12mm / 0.5" and 75mm / 3". You can add as many marking arms as you wish. Ten is a good place to start, but if you're working on something really big, you can expand as needed. Also, the modular design means you can add or subtract later. The longest pieces are about 112mm long, so this should fit on almost any printer.
