Description
This is the first FDM-printable 1:64 scale excavator, inspired by the JCB 245XR.
Constructor 1/64 Series – Fully Functional Excavator
This model is part of the Constructor 1/64 Series, a lineup of realistic, FDM-printable construction equipment designed for both play and display.
The model is fully functional, with moving cylinders, tracks, boom, and bucket, designed to replicate real excavator motion at a compact scale.
Durability was a top priority during development. The design has been tested by real kids—two young boys played with early versions, and multiple improvements were made to strengthen high-stress areas. The result is a model sturdy enough for careful play, while still detailed enough for display.
No AMS required.
