At the end of Efficiency Distributions (the warehouse level) when you go to enter the cargo bay door code, I really wanted to bring my arrows with me. Well it turns out you can!

Drop all of your items on the ground outside the Mantrap (the item deleter in the tiny room) and pass through and enter the cargo bay door code. From the pin pad, reach into the elevator and pull the lever without actually stepping inside.

This triggers the elevator doors to close and Winta to start talking over the earpiece leaving you behind. Quickly go back out to the other side of the Mantrap and collect your items off the ground. After she finishes talking, you will load into Fabrications with a whole inventory of arrows.

It shouldn't come as any surprise, but they are useless against ADAM so I suggest you save them for Cost Optimizer Core to kill the Cost Optimizer Guards and make the fuse power level puzzle less stressful.
