Step 1: You will need to have

unlocked the statue for building, from acquiring the

picket fence magazine.

(Found in Saugus Ironworks)

Step 2: Make sure to have some copper

shipment.

(Found in Diamond City from Vendor Arturo)

Step 3: Be sure that your toolbox is cleared out.

(Not sure if works in other settlements other than Sanctuary Hills)

Step 4: When open in toolbox menu, hit Triangle then Square fast (PS4), Y then X fast(XboxOne).

(This will duplicate the copper shipment)

Step 5: Put your copper shipment away safely for later reuse,

keep the duplicated copper inside your toolbox.

Step 6: Go into build mode: start spam building statues, try build closely in rows (this is for easier removal for later on)

Note: You may want to duplicate copper shipment via Dogmeat duplication method, so that your copper stacks faster in the Toolbox duplication process. As you saw I had 17.

Step 7: For fast statue removal press Square & X at the same time (rapidly), X & A (Xbox One)

Enjoy! You gain about 2 levels every 5 minutes, keep building and removing, restock copper if needed. Also if you want more building space just do the settlement space glitch, links and info related to this exploit can be found by youtube searching k deck gamer or doing a specific search for the glitches/locations.
