A 3D model of an Ender 3 3D printer designed for simulating and checking physical upgrades before 3D printing them. The model employs a non-destructive workflow using modifiers such as Array, Bevel, Boolean, Mirror, Screw, and Solidify, allowing for easier structural adjustments.

It features accurate representations of the printer's components based on the 2019 hardware revision, including the glass bed, extruder feed gear, and motherboard. Parent relationships and axis motion constraints are configured to reflect the printer's mechanics, alongside placeholder wires to ensure appropriate clearance when designing custom modifications.
