Designer: Satya SchiavinaSchool: SAICE University3D Printing Method: FDM on a Creality Ender 3d printerMaterial: PLAProblem :The standard and commonly available corrective lenses for SCUBA diving masks have several limitations. They are attached to the glass pane inside of the mask and therefore can’t be moved around. The field of vision and the viewing angle is therefore also limited due to the position where the corrective lens is fixed on the glass pane. On the other hand, a movable lens as the one proposed here, allows one to change one’s field of vision according to one’s requirements. This project is my way to fix and overcome all these limitations by making an add-on, movable and adjustable lense design. Redesign:One of the challenges of designing an add-on frame to a diving mask is the irregularity of the shape of a diving mask. The shapes of a typical diving mask are mostly curved with complex three dimensional forms. Thus I used the power of photogrammetry to recreate a mesh of the mask, giving me the form to build the 3d printed frame around.To move and slide the lenses up and down the frame, a geared mechanism with a pinion that moves on a linear guide with a rack, was conceived. All the cad and simulation tests were done in autodesk fusion 360.3D Printing Process:All the parts have been modeled with respect to ease of 3D printing. A considerable amount of time went in designing the parts keeping in mind the structural strength of the parts as well as the feasibility of 3D printing. Ideally, I would have liked to print fewer parts, but I had to split some of the parts into smaller units because it was not possible to print those parts in one go.I have sliced the model in a way that no component has any overhangs and thus can be printed without supports. The complete list of the parts with their 3d printing specifications (stl's and g-codes) are in the file above.Further details regarding the assembly of this project can be found on my build guide on instructables : https://www.instructables.com/id/Diving-Mask-With-Custom-Add-on-Lenses-V20-Made-Usi/
