THE WORKSHOP / ALL THE DETAILS

Your build starts
with a closer look.

Explore the design, inspect the components, then take the prototype files into your own workshop.

Digital prototype R4. CAD and cut outlines are starting geometry. Verify fits, loads, material suitability, guard retention and clearances before manufacturing. Physical food-release, refrigeration and outdoor validation remain open. The original R1 engineering studio is preserved; its checks do not certify the revised R4 assembly.
