Imperial Scribe

This thing is manly used for construction or home DIY on wood to scribe cut lines. The ruler sizes are 1in., 2in., 4in. and 6in. with marking spacing of 1/8in. All the rulers use one base, so just re-place with the one you need. They all fit tight in the base and with the hold-down arm the rulers stay in-place. The rulers have slots for a construction pencil and holes for a pen or regular pencil. The outside of the rulers are set to 1 1/2in. which is the width of a 2x4. and have a centre V which marks the centre of the 2x4.

I used the 0.4mm nozzle to make these but the 0.3mm nozzle would be better to use. That's why the small layer height and wall count.
