Ecto Goggles - I Made Another Ghostbusters Prop
March 11, 2025A few years ago, I made this proton wands for my kids so they could dress up as Ghostbusters for carnival.
But frankly, it might have always been me who was most obsessed with Ghostbusters. See "exhibit A" below.
So, for this year's carnival season, I decided that I had to extend this costume with yet another prop and built a pair of Ecto Goggles.
A quick web search revealed that plenty of other people had had this idea already and I found this instructable which I mostly stuck to.
Part List
Here is what I used.
- Welding goggles: I ordered these.
- Acrylic sprays/colors: I used matt camou-green for the googles, matt black and metallic for the tubes.
- Wires, LEDs and a switch.
- A case for two 1.5V batteries.
- Screws and bolts for visual effect.
- Access to a 3D printer: I modelled the base plate and the tubes on Tinkercad.
The Build
First, I printed the 3D models that I had created with Tinkercad.
Then, I gave the printed tubes and the plate a coat of acrylic paint (i.e. filament color did not matter here). Only the "lenses" needed to be printed with a transparent material, as the LEDs would sit behind those later.
As a next step, I wired up the electronics. Two green LEDs need to go into the tubes and a red one will sit next to the on/off switch. A battery case with two 1.5V batteries is powering the circuit.
Then, I glued the LEDs to the "lenses" and all parts together as seen on the picture below.
After that, I disassembled the newly-bought welding goggles and removed the actual glass sheet (that is meant to protect your eyes). Then I sprayed the goggles with camou-green acrylic paint and glued in the plate and battery case from the picture above.
Finally, for effect, I added a couple of screws, knobs and bolts and also some stickers linked on the Instructable.
Done!
