Parts Library
Discover the growing parts library behind MobilityShield, where real printable components, Builder-ready geometries, and direct STL assets start to form a serious modular system.
How the library and Builder fit together
Builder gives MobilityShield movement. The Parts Library gives it shape. One lets you open parts directly; the other helps you understand the growing system behind them.
Plates & Frames
These plates and frames are where the library starts to feel serious: strong base geometries, clear mounting logic, and the kind of printable structure that makes a modular system believable.
Rectangular Frame
Open in Builder →
Triangular Plate
Open in Builder →Trapezoidal Plate
Open in Builder →Circular Plate
Open in Builder →X Cross Plate
Open in Builder →
L Plate
Open in Builder →T Plate
Open in Builder →U Plate
Open in Builder →Strips & Curved Members
Straight and curved strip parts make the system more flexible, opening the door to lighter assemblies, perimeter forms, and more varied mechanical layouts.
Strip
Open in Builder →Strip with Slots
Open in Builder →Circular Strip
Open in Builder →Curved Strip
Open in Builder →Curved Strip with Slots
Open in Builder →Brackets, Braces & Structural Connectors
This is one of the categories that most clearly upgrades the project’s credibility: not just shapes, but the structural parts that make assemblies feel intentional and buildable.
Angle Bracket
Open in Builder →Angle Girder
Open in Builder →Corner Brace Square
Open in Builder →Corner Brace Triangular
Open in Builder →Flanged Plate
Open in Builder →Volumes & Enclosures
This category marks an important shift in the library: from planar parts to parts that begin to hold space, contain components, or define volume.
Open Box
Open in Builder →Mechanical Parts & Profiles
These parts are where the library starts to feel less like a printable toolkit and more like the early language of a real modular machine system.
Gear
Open in Builder →Extruded Profile 15x15
Open in Builder →Direct STL Files
These STL files make the library feel more tangible by sitting closer to final printable output, not just editable geometry.
