LEGO Green Goblin Costume

Hampton Comicon 2021 was the first convention we attended after the Covid-19 shutdowns. With Spider-Man: No Way Home about to release and William Dafoe returning as Green Goblin, I thought Green Goblin would be a good choice for a costume.
Just before the beginning of the 2020 pandemic, I bought a 3D printer. During 2020 and 2021 I got more familiar with using the 3D printer and making/editing simple 3D models. Fortunately I found a 3D model of the pumpkin bomb that I liked. I altered the model to add a connector that allows me to unscrew the top half to add electronics and recharge the battery. I added LEDs and a microcontroller that is controlled by a Bluetooth app on my phone to trigger the “detonation” sequence.
I built the Green Goblin mask to go over the normal LEGO head peg. The mask had a lot of different pieces that I had to try to figure out. Since I wanted to do something as elaborate as the Iron Man lifting face, I did consider making the eyes flip open to reveal LEGO eyes underneath for about 2 days before I realized it would be too complicated and time consuming. Instead I decided to 3D print the eyes. At first I was little disappointed that whey weren’t as round and smooth as I wanted but I grew to like how the light hit the different polygons. Since making this costume, I’ve learned new ways to round and smooth out 3D prints so in the future I would do it differently. The eyes are attached to the head peg and the mask slips on over the head which gives it that sunken in look. The mouth is covered with a piece of clear plastic with black car window tint. This gave my son the most visibility of any of his recent costumes.
Since we made this costume for the October Hampton Comicon 2022 show, we decided to have our son hand out candy at Halloween in costume.

The detonation sequence is triggered by a Bluetooth app on my phone. The sound effects are controlled by the same remote control key fob I used to trigger the Iron Man face.
