I don't want to be here forever, so quick and dirty.

Step 1: Look for vending machines that sell items for 10 Eddies.

Step 2: Buy all the items from it.

Step 3: Rinse and repeat as much as you can.

Step 4: Go into the inventory, disassemble all the consumables you just bought. If it costs 10E a piece, you should receive +6 common craft components and +3 Uncommon craft components. NOTE: Sometimes the prompt at the bottom right to disassemble won't appear, you can still disassemble these items, just hold the required hotkey.

*WARNING*: The regular NiCola can't be disassembled, make sure when you buy from NiCola machines to choose the second or third option on the pad. (edit 1)

Step 5: Now that you have thousands of Common/Uncommon crafting components, all you need to do is build the Uncommon Nekomara. Having the related crafting perks in regards to saving components is mostly QOL, as eventually you'll farm all the components you need. For min-maxing, consider disassembling the rifles to reuse components. Otherwise, at level one crafting they sell for 325E, increasing as your crafting skill improves.

Step 6 (Optional): Sell the Nekomara's at drop points, each drop point has 20000E to give.

Step 7: Farm those Eds!
