Currently the final 2D drawing are under review, but you can consider what attached at the end of the Technical Attachment, together with information written inside the various paragraphs, as a reliable indication about main expected tolerances and surface requirements.
3D models, on the other hand, are very close to the final version and we are pleased to attach here a package of STEP format files containing the parts as solid bodies.

Considering that they are left to the Supplier the tasks to finalize the optimal/preferred manufacturing technologies in term of metal parts construction and treatments (from forgings, from plates, from additive, etc…, with proper assembly solution like welding -including optimized chamfer shapes- and specific surfaces treatments), it is expected that the geometries should accomplish specific constraints that must be taken into consideration to get the required performances, qualifications and technical requirements.

All the geometries and processes, updated and designed accordingly to the requirements, shall then be defined under the Supplier’s responsibility and must be recorded on the relevant documentation (3D Models, 2D Drawings, Manufacturing Procedures, Operation Instructions, Control Plans, etc..) and delivered to DTT as part of the supply.
