INSTRUMENT ØØ1: Inspired by split-flap displays at railway stations, TROPOS is a desk calendar designed to mark each passing day and month with a simple turn of the knob. From the Greek tropos (turn, change, shift) and from the troposphere - the layer of sky closest to us, where clouds drift, winds shift and movement never stops. With TROPOS, every day you get to begin again. • Made to order • Every TROPOS provides two different font options for the MONTHS flaps. • Made entirely with polylactic-acid (PLA), a sustainable material derived from corn and sugarcane. • Comprises a total of 86 parts (no assembly required) 180 mm x 53 mm x 85 mm265 g • IMPORTANT NOTE: Flaps can only move one-way (downwards). Please refrain from turning the knobs upwards to avoid damage. Flaps will descend when the knobs are turned downwards. • Keep your instrument away from direct heat sources and prolonged sunlight • Clean gently with a soft, dry or slightly damp cloth. Avoid abrasive cleaners or scrubbing. • Handle the parts with care, do not force adjustments. • Small surface variations, layer lines on casings, filament specks on flaps are part of the 3D printing process and contribute to each instrument's unique character.
