3D Cartesian Coordinates - Assembly

A X,Y,Z axis Coordinates System ready to assemble.
This design is meant to aid young students to conceptualize objects in space.
In particular it's meant for blind students, hence the markings on every 1 centimeter, letters and positive/negative signs.

Each axis "arrow" has 12x12x150 mm and the central connecting cube has 14mm side.

The design has no tolerance, so the fitting is snug and tight.

Printed on a BambuLab A1 Mini, Smartfil PLA and 0.16~0.20 layer height. Dual color in the markings.
