Printable parts and source CAD for the Tiny Engineer desk robot.
The full assembly — all components composed — lives in cad/TinyEngineer.f3d (Autodesk Fusion). Open that file to adjust the model or adapt it to different hardware sizing (e.g. different servos).
Individual parts are exported to parts/ as .3mf files. They are ready to print in an orientation that does not need supports. Print with PLA or PETG.
Assembly uses a bunch of 2 mm diameter screws — no glue. Easy to dismount and modify later. Exact screw lengths/counts and full assembly steps are not documented yet. Use the part table below, then electrical and bring-up docs.
