3D preview

Preview not available yet. A model has not yet been prepared and approved for display on this page. This does not mean the project lacks CAD files; see Source files and licenses for the reviewed source availability.

Assembly and use

Mounting and application

Designed for Hangprinter cable robot; no cobot/delta mount verified. [S001] [S002] [S003]

Before sourcing the build

1–2 kg/h is listed as a design driver, not independently verified throughput. The README calls for a drill bench, soldering, 3D printing and CNC access. It warns about mains-powered mica band heaters and electric-shock, burn and fire hazards, recommending experienced electrical help. Reconcile the heater/power package, feed system, moving mass and robot synchronization. [S001] [S002] [S003]

Files and reuse terms

CC-BY-SA-4.0 license and README; a template badge says MIT and should not override the license. [S001] [S002] [S003]

The pinned inventory lists Fusion 360, IGES, STEP and Inventor files, without identified BOM paths. CAD availability was assessed from that inventory; fabrication suitability was not validated. Establish a configuration-specific purchasing list and matched control sources, including the separate reuse terms of purchased components and controls. Current delivered cost and measured performance are not established; no hardware was built or tested for this profile.

Cost

No current, complete configuration-specific build cost has been established for this profile.
