Diving Mask with Custom 3D Printed Add-on Lenses

Designer Satya Schiavina from SAICE University employs FDM on a Creality Ender 3D printer to produce PLA parts. Problem: Standard corrective lenses for SCUBA diving masks are limited in several ways. They are fixed to the glass pane inside the mask, preventing movement and limiting field of vision due to their fixed position. In contrast, a movable lens allows users to adjust their field of vision according to their needs. This project aims to overcome these limitations by creating an add-on, adjustable lense design. Redesign: Designing an add-on frame for a diving mask is challenging due to its irregular shape. Typically curved with complex three-dimensional forms, the mask's shape requires photogrammetry to recreate a mesh for building a 3D printed frame around it. A geared mechanism with a pinion that moves on a linear guide with a rack was conceived to move and slide lenses up and down the frame. CAD and simulation tests were performed in Autodesk Fusion 360. 3D Printing Process: All parts were modeled with ease of 3D printing in mind, considering structural strength and feasibility. Ideally, fewer parts would have been printed, but some had to be split into smaller units due to printing limitations. The model was sliced to prevent overhangs and supports, allowing for printing without them. The complete list of parts with their 3D printing specifications (STLs and G-code) can be found in the file above.
