paper thin 21cm ruler

thingiverse

This 21 centimeter ruler is remarkably thin, making it perfect for printing with two distinct filaments. This contrasting effect allows the tick marks and numbers to stand out clearly against the background. To achieve optimal results, I highly recommend using the highest resolution detail setting available. If you only have one extruder at your disposal, simply pause the print after reaching the 0.5mm mark on the z-axis. Then, switch to the second filament color once printing begins at the 0.55mm level. This clever technique ensures a visually appealing and professional finish. As it happens, there are numerous rulers available online, but this particular design stands out for its remarkable efficiency in terms of filament usage. I often print these up for individuals who need to replicate broken items in Tinkercad, providing them with accurate measurements in the process. This is an excellent choice for educators working with a classroom full of students, as it offers a cost-effective solution for distributing multiple rulers.
