How are people getting 300 points each time? I only see 143 points for Crafting: Inventor.
Further, you have to craft 50 items to get the points so that is 8.3 (50/6) runs to get the objective. If you are getting 300 per objective, then you have to hit it 50 times to get to 15000 command points. That is 2,500 medpacs (50*50).
The archived medpacs require 2 cell grafts to generate 6 medpacs. Taking the lowest level cell graft as an example - dielectric cell graft - that would require 4 total of each of 3 components (cell fiber, green goo and hyo-syringe). In other words - 12 components to make 6 medpacs. Based on the above that is 5,000 components.
This doesn't seem easy to do.
