A clamp and bushing concept was pursued in lieu of early ideation involving permanent alteration to the bowl. The clamp would allow different bowl profiles to work with a single design, making the project more accessible and repeatable.
Details were refined to reference the iPhone form language. Width and corner dimensions were taken directly from the iPhone design to create a seamless transition between product and accessory.
The clamp initially consisted of a cap, felt bushing, and routed base with varying widths. After fabricating a prototype, the design was revised to be made from a single plank of 3/8" wood. This important revision made fabrication quicker and simpler, and resulted in a more refined aesthetic.
The resulting design can be made with basic woodshop tools and supplies at low cost using the project details published on the Instructables website.
