01. Educational Content & CAD Modeling Directives

All parametric constraints, dimensional boundaries (such as volume limits, primitive count maximums, and mechanical tolerances), and design challenges featured across our project cards are designed to stimulate creative problem solving and instructional design thinking. They do not constitute formal engineering advice, architectural blueprints, or certified manufacturing specifications.

Users, educators, and makers are solely responsible for testing, validating, and verifying the structural integrity, dimensional accuracy, and mechanical viability of any CAD model, 3D printed object, or physical prototype prior to implementation in real-world or safety-critical applications.

02. 3D Printing, Fabrication & Workshop Safety

ConstraintCraft Project Cards assumes no liability for hardware damage, material failure, machine malfunctions, physical injuries, or losses arising from the fabrication, slicing, 3D printing (FDM, SLA, SLS), laser cutting, or CNC machining of models developed using our constraint prompts.

• Always observe appropriate workshop and laboratory safety protocols when operating 3D printers and fabrication machinery.
• Verify material safety data sheets (MSDS) when using photopolymer resins, specialized filaments, or chemical post-processing agents.
• Supervise students and minors during all physical testing and manufacturing workflows in educational makerspaces.

03. External Third-Party References & Trademarks

References to specific CAD software tools, slicing platforms, or hardware ecosystems (including Tinkercad, Autodesk, Fusion 360, Blender, or standard 3D printer hardware) are included strictly for compatibility description, instructional clarity, and pedagogical context.

ConstraintCraft Project Cards is an independent educational initiative and is not affiliated, endorsed, sponsored, or certified by Autodesk, Inc. or any other referenced commercial software vendor. All product names, logos, and registered trademarks belong to their respective owners.

04. Limitation of Liability & "As-Is" Warranty

All content, templates, downloadable project card briefs, and interface tools are distributed on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind, whether express or implied. ConstraintCraft Project Cards makes no guarantees that our resources will meet specific syllabus requirements or deliver uniform results across varying classroom environments.

In no event shall ConstraintCraft Project Cards or its contributors be liable for any direct, indirect, incidental, special, consequential, or punitive damages resulting from the use or inability to use our platform and published materials.
