Here's the plan. We're going to create a sort of double loop design. The positive loop around the base, and an elevated negative loop. These loops will be constructed of bare copper wire, each one connected to its respective lead on the battery. What I did here was construct a parallel circuit, wiring 4 leds to one 3v watch battery. I would suggest wiring up the 4 leds to the battery on a breadboard before assembling it in 3D.

If you feel like you have to flex too hard to get the system to trigger, you have a couple options: This is the obvious major step in this build, and you're welcome to stop after this step. Especially if you print the glove in red filament, you could make a similar build for a lot less work, but it won't have as nice a finish or color. It should be fairly self explanatory, but here was my process:

Put on the glove and hold the finger armor pieces in their intended place to see if they are too big/small Next I used my dremel rotary tool. I had this from a previous project, so it was convenient for me. You by no means have to use a fancy tool to sand, in fact I also used some sand paper by hand later on. use whatever tools you have available to you, and are comfortable using.

Position the speaker between the top and bottom upper palm pieces and cut out a circle in the top piece smaller then the diameter of the speaker. Paint the parts! Now you're ready to start painting. Just remember to DO LIGHT COATS. I can't stress this enough. In past projects, I've painted it too heavy and it just started running and dried weird. It was fine, but for just a little more effort it can come out so much better. You might need to repeat this step a few times before you get the scale correct. The armor in this tutorial was increased by 10% and then trimmed one at a time to get the fit to feel correct. Connect a 3v power supply to the breadboard. This could be the 3v watch battery if you have a holder that can plug in, it could be a 2 cell AA battery holder, which would provide a total of 3v, or it could be a bench power supply set to 3v, to name a few options. You'll want to test the MyoWare to be sure it is setup correctly before uploading the new Arduino code.

Then place 3 more leds "in parallel" to this first one, the positive leads on one row, and the negative leads on another. You really really really should rough up the general surface before painting to ensure a strong bond. Find the model on thingiverse: https://www.thingiverse.com/thing:1779274 I used the models here. Big shoutout to DaDave for compiling this epic suit of 3D printed Iron Man Armor! I only printed the main hand piece, fingers, and the center disk, but you're welcome to print even more of the armor! As the foam seals, you should be able to see the foam turn slightly shinier. Makes it easy to tell were the hot air has passed over already. Shake the can and spray the box a bit. Get a feel for the trigger, the distance, how fast it colors, etc.
