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

Printer-derived extrusion subsystem; no robot-arm mount established. [S001] [S002]

Before sourcing the build

Choose one motor/revision. V1.4 filenames distinguish NEMA17/8mm and NEMA23/12mm; later revisions contain STEP, printable and laser-cut artifacts. These filename clues do not validate dimensions or fit. The README links the FabLab München wiki and fabmx.org; their parts lists and assembly coverage still need review. As an adaptation checklist, verify the chosen feedstock’s processing requirements—including whether debinding and sintering are needed—and establish compatible controls. A CAD family is not one bill of materials. [S001] [S002]

Files and reuse terms

README explicitly grants CERN-OHL-P v2 despite no GitHub license classification. [S001] [S002]

The FabLab München resource is an upstream-linked starting point, not a build guide verified by this review. They do not establish a complete, matched mechanical and control package. 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.

Source files and licenses
