3D Drawings & 3D Printing | 3 Hardware Pieces -- Version 2

I have 3 hardware pieces that need to be drawn in 3D formats and then printed using a 3D printer. The 3D file formats that need to be delivered are the following: .stl; .sldprt; .sldasm; .step & .pdf. The drawings will have at least 1 revision set before the drawing deliverable is considered complete. The drawing deliverable must be completed on or before 04/15/2019. The 3D printing deliverable needs to be completed on or before 04/18/2019, with shipping to occur to the U.S. on or before 04/18/2019. The cost of shipping to the U.S. must be included within your quote. The project will have 3 milestones. 30% paid when drawings are completed and delivered in the specified formats; 50% paid when the 3D printed items are completed and shipped [photos provided along with proof of shipping]; 20% paid when the 3D items are received, inspected and approved.
