Go to the model store to buy a pair of flat-nose pliers, a hardware store to buy a set of small files and sandpaper, and a drugstore to buy absorbent cotton. Use the flat-nose pliers to cut out the parts. Don’t cut too hard, try to leave some margin. , then lightly polish it with a file. When approaching the surface of the part, use No. 2000 water sandpaper dipped in water to polish (pay attention to the sanding area, do not scratch other places), and then use absorbent cotton dipped in toothpaste to polish, with the purpose of restoring the parts. The original smoothness and gloss can be assembled according to the drawings. Model making is a test of whether your brain is flexible. Spending the least money and doing the best work is the embodiment of your ability.
