Iron Man arm assembly guide
Things you’ll need:
3D Gloop adhesive is a type of bonding material designed to hold objects together in three dimensions. It works well for projects that need glue with a bit more strength and flexibility than regular adhesive. People often use it for crafts, repairs, or anywhere a reliable, solid hold is necessary.
Glove
3d printed parts
Small Round 12V LED
Wiring
Zip ties or other fasteners
Instructions
Step 1: Main arm
Take the two main arm parts and turn them until all the details line up, then use some glue to secure them. Put the hand cover onto the main arm structure. Use zip ties or whatever fasteners you have on hand to hold it tight
Step 2: lighting
Stick the Arc Reactor cover onto the glove with some adhesive.
Pick a small LED light that can fit inside the reactor housing.
Run the wiring up inside the arm carefully, making sure it stays neat and out of the way.
Step 3: Put the hand on
With the glove on, spread some adhesive on the hand part.
Hold the hand to the glove, making sure it’s snug and lined up right with your fingers.
Step 4: Connect the Fingers
Put adhesive on each finger one at a time.
Attach the fingers gently, making sure they look natural and move properly.
Give the glue enough time to dry.
