Cartesian coordinate system snap together

thingiverse

This object teaches students about coordinate measuring machine basics by demonstrating translations, rotations, and other alignments through its coordinate system axes. Initially, screws were used to attach the arrows, but a snap fit pin construction was implemented instead to avoid unsightly holes. However, the vertical snap pin needs to be printed separately due to insufficient strength in that orientation. Plexiglas tubes (30mm long with an ID of 16mm) are added for protection and appeal, glued to the cube's body but not the arrow, after being secured with UV curing glue. The model was designed using OpenSCAD and the pin connectors library, although the file is still considered messy by the designer. Print settings include a RepRap Kossel printer, no rafts, yes to supports, 0.2mm resolution, 25% infill, and notes to use supports for overhanging snap pins, as they will be hidden after assembly.
