Print Profile(2)
Description
This DIY PET Bottle Costume Backpack is a modular backplate designed to hold two PET bottles and turn them into a creative costume accessory.
The backplate is available in two sizes:
- Standard version
- Mini version, optimized to fit the Bambu Lab A1 mini
Simply use 1 L or 1.5 L PET bottles, decorate them however you like (scuba tanks, jetpack, astronaut gear, fantasy props) and screw them directly into the plate.
To wear it, thread elastic bands through the slots, adjust the fit, and the backpack is ready to use.
At the top, the backplate includes ports that allow you to attach 5 mm or 10 mm hoses, making it easy to add a mouthpiece, tubes, or other costume elements.
Perfect for:
- Scuba diver costumes
- Jetpacks
- Astronaut or sci-fi outfits
- Creative DIY and carnival projects
No real equipment — just lightweight, safe, and playful DIY fun.
Have fun!
