Provision of a removable frame
Complete Frame Design
Nonfunctional Requirement
Physical integrity and artistic appeal is improved by provision of a removeable (and user replaceable) bumper frame, made of colourful plastic.
This relates to the requirement of individual hackability, by encouraging the owner to make their own frame at home using affordable tooling and standard materials. Alternatively, the user can remove their frame, substitute a different kind, or replace it when damaged.
Assumptions
The already user has experience with 3D printing.
Constraints
The design is appropriate for printing on digital light processing (DLP) and stereolithography (SLA) machines, due to artifacts like overhang, wall thickness, and other geometry.
