3D Printed Nut and Bolt

3D modeled nut and bolt to be printed

The Original nut was designed with a tolerance of 0mm

After making the first edition of the print, the thread was changed to 24x2 and with an added tolerance of .02mm

Finished nut and bolt after being printed

Both items were printed successfully and fit together well.

Roller Chain Challenge

Roller Chain Modeling Challenge

Time - 4 Class Periods

Challenge Objective - 3D model a roller chain link of your own design and print a series of five links without print supports. When completed, the link should move as a roller-type chain.

Criteria

Must be designed in SolidWorks
Prepared in a slicer for additive manufacturing
3D printed in PLA filament
An individual link cannot take up more space than 20mm²
Test prints (no more than two links) are required before full prints (no more than 5 links)
No slicer-generated supports allowed

Presentation - Place on the Additive Manufacturing page.

(20%) Display challenge instructions (this document) for the viewer to understand the challenge.
(40%) Images and GIFs of modeling/design methods (showing yellow preview) of the link and assembled chain (SW and 3D printing)
(20%) ePort Posts - Images of the notebook designs, GIFs of modeling designs (in SolidWorks), slicer images and additional information
(20%) Final Design - a full print moving the links in your hands (as a GIF)
