SendCutSend's Parts Builder is a free, web-based parametric CAD demoed by CTO Jacob Graham that accelerates simple part design (washers, brackets, patch panels, gears) via editable templates, color-coded bend lines, material selection (e.g., 0.060"), auto-correcting hole operations, and gear/trigger-wheel generators (configurable tooth counts/missing teeth). It supports on-device edits and links to Design Services for complex jobs.
