Slide Rule

thingiverse

A minimalist slide rule design takes shape. The upper and lower slides are merged into one, secured by 4-40 screws (3 mm) that hold it firmly in place. Tapping #2-56 screws into the cursor's upper and lower supports requires precision, with three screws per side, middle and outer, providing a sturdy foundation. A 0.030" clear PET reticle adds clarity to the design, suggesting countersinking of screws for a seamless finish. Meanwhile, work continues on a plotter fixture that will bring fine drafting pens into play, accurately drawing lines onto the slide rule's surface. Fabricated from PLA, this slide rule embodies simplicity and functionality in equal measure.
