Tent Ruler
A minimalist ruler design whose triangular, tent-like shape makes it easy to handle as well as serving as a pen or pencil holder.
Everyone has problems when lifting a flat ruler from the paper because it slips off. With Tent this doesn't happen anymore, because thanks to its shape you can easily pick it up.
It is a 15 cm ruler, with markings every centimetre, so it can also be used for measuring.
Printing It has been designed so that it can be printed without the need for supports. I used a layer height of 0.15 mm and a 100% infill or cover the entire thickness with wall lines.
