“…Prior work has shown that novice users may face multiple challenges while discovering or using public 3D designs on Thingiverse [2,16]. Since novice users tend to use online communities to fnd designs instead of learning 3D modeling, it is important that available design information and metadata should be organized in a clear and easy-to-understand manner to avoid potential confusions [5].…”

Online 3D model repositories such as Thingiverse ofer millions of open source designs that are shared for reuse and remix. Many of the designs are customizable to adapt to real-world objects upon personal needs of varying tasks and physical dimensions. However, it is challenging for novices to discover such designs using textbased search queries, comprehend what each parameter means for customization, locate these parameters on the target objects for measurement, and conduct measurements correctly. These challenges may cause the designs to be incorrectly adjusted, thus failing to function as expected and requiring users to start over, which costs additional time and material. We present CustomizAR, a pipeline for facilitating the interactive exploration of adaptive designs and the measurement of real-world constraints to fabricate them correctly. CustomizAR supports the search and discovery of adaptive 3D designs using an object-centric graph-based data structure, and guides users through an interactive measurement process leveraging computer vision techniques. Our technical evaluations and user studies demonstrate that CustomizAR facilitates efective discovery, adjustment, and reuse of adaptive designs that are shared online.

“…Creating mounts and fixtures for various objects is a general use-case made easier by easily accessible, low-effort Ephemeral Fabrication devices. Usually, when relying on CAD, the referential use of an object involves either scanning, measuring, or recreating the artifact in a different fashion [47]. This is not necessary when the object and the malleable material are allowed to interact.…”

Personal fabrication empowers users to create objects increasingly easier and faster. This continuous decrease in effort evokes a speculative scenario of Ephemeral Fabrication (EF), enabled and amplified by emerging paradigms of mobile, wearable, or even bodyintegrated fabrication. EF yields fast, temporary, in-situ solutions for everyday problems (e.g., creating a protective skin, affixing a phone). Users solely create those, since the required effort is negligible. We present and critically reflect on the EF scenario, by exploring current trends in research and building a body-worn fabrication device. EF is a plausible extrapolation of current developments, entailing both positive (e.g., accessibility) and negative implications (e.g., unsustainability). Using speculative design methodology to question the trajectory of personal fabrication, we argue that to avert the aftermath of such futures, topics like sustainability can not remain an afterthought, but rather be situated in interactions themselves: through embedded constraints, conscious material choice, and constructive embedding of ephemerality.

“…There is a disconnect between the location of artifact design and the artifact's future location [4,37]. This requires either assessment and transfer of requirements, or methods to compensate measurement errors [27], which is a challenge that is not exclusive to novices.…”
