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

README explicitly targets Rostock mini, a delta-printer application. [S001] [S002] [S003]

Before sourcing the build

Experimental design. Confirm syringe dimensions, exact motor/60 mm stroke option and pressure/flow limits; no general delta pick-and-place or cobot compatibility claimed. [S001] [S002] [S003]

Files and reuse terms

The license.txt file states CC-BY-NC-3.0, including attribution and a noncommercial restriction. Intended commercial use requires rights clarification. Separately selected controls and purchased components need their own source and license review. [S001] [S002] [S003]

The inspected inventory lists STL and OpenSCAD files, including baseplate and syringe-holder parts, without an identified BOM. The CAD was not fabrication-validated, and a complete matched mechanical/control package remains unestablished. 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

CC-BY-NC-3.0 in license.txt. Experimental design. Confirm syringe dimensions, exact motor/60 mm stroke option and pressure/flow limits; no general delta pick-and-place or cobot compatibility claimed.
