This week, I completed the final prints of both the faceplate and front plate and thoroughly cleaned all remaining support material, sanding the edges to prepare for the installation of the internal neoprene comfort layer. After etching the surface, I adhered the neoprene lining inside the faceplate and verified a smooth, secure fit. Modified and newly printed fittings, inserts, and TPU wire plugs were finalized to ensure proper installation of the front assembly onto the head strap. Due to 3D printing tolerances on the final print, i manually filed the IR sensor mounts on the front plate to achieve a precise fit for each sensor. I also revised the dimensions of the battery tray cover, printed the updated version, and validated its fit with the internal components.
On the website, I updated the submenu and page title from “Validation” to “Final Testing and Results” as well as created a new Google Sheet to document pass/fail outcomes based on the Engineering Requirements section.
For the design report, I added a full set of appendice titles—including program code, datasheets, engineering standards and compliance codes, and the user survey—and reorganized tables and figures to follow a chapter-based numbering convention for improved clarity. I adjusted the placement and size of the project title and design logo to ensure proper alignment and visual consistency. Engineering component images were moved from Chapter 1 to Chapter 2 to better match the report structure. I also reorganized and renumbered all pages in Chapters 1 and 2, removed outdated or invalid project limitations based on Dr. Ejaz’s feedback, and updated the budget documentation to reflect accurate cost, projected cost, and the full cost to build a complete NAVI unit. Chapter 3 is in development alongside Chapters 4 and 5 to finalize the report.
