“At the rear of the Mark III armor’s legs, the stabilizer flaps can be raised to reveal the internal structure. These pieces correspond to that area.”




Materials: All of the parts in this issue are plastic.

The Left Leg (3)

Stage 1 – Fitting the Circuit Board
Step 1

Retrieve your Inner Leg Support Frame from the previous issue. Slide the narrow end of the Inner Leg Circuit Board through the ‘hoops’ of the Support Frame, as shown:

At the narrow end of the Circuit Board is a small hole that fits up onto a pin of the Support Frame:

Step 2

Secure the Circuit Board to the Support Frame from behind with two (2) IP screws:

Once I assembled this section, I realized this section of the model is revealed when the leg flaps are opened. Since the Circuit Board (and the small parts that will attach to it) are mostly silver, I wanted to add some additional color to these bits. Therefore, I disassembled it and used a mix of red, yellow, green, and blue Artistro acrylic paint pens, my Metallic Sharpies, and my Molotow Chrome Pen to ‘paint’ many of the details on these parts:

Stage 2 – Positioning the Circuit Board in the Leg
Step 1

Retrieve your Left Leg assembly from the previous issue. Fit this Circuit Board assembly inside the lower leg, aligning the screw holes.

NOTE: You may notice extra wiring in the pictures below. These are part of my custom Central Lighting mod.

Secure this Circuit Board into place with three (3) EM screws.

This is your friendly reminder to try using 3-in-One Oil on all screws going into metal:

Stage 3 – Assembly of the Inner Leg Mechanisms
Step 1

Press the two pins of a Inner Leg Mechanism (41B) into the two matching holes along the top edge of the Circuit Board, as shown.

The pins/holes of these parts are different sizes, so they will only fit together one way:

Step 2

Repeat this process for the three remaining Inner Leg Mechanisms in the same nearby holes:

When the leg is upright and the ‘flap’ is open, hopefully this section will be more colorful inside:

Step 3

Press the D-shaped pin of the Inner Leg Mechanism (41D) into the matching hole at this location of the Circuit Board, as shown:

Step 4

Press the two pins of the Inner Leg Mechanism (41C) into the matching holes at this location of the Circuit Board, as shown.

Again, these holes are different sizes to ensure the correct orientation:

Step 5

Finally, press the end pins of the Inner Leg Mechanism (41E) into these matching holes of the Support Frame, as shown.

We used the Molotow Chrome Pen on the thinner shaft of this part to give it that ‘hydraulic ram’ shine:


Adding color to small details like these really make this build fun! I am not sure if I will display my Iron Man with these flaps open, but it is great to know our work is in there ready to be seen.
