RFID blocking wallet (TPU)

thingiverse

The wallet features two slits at its bottom, designed for the effortless insertion of aluminum inserts. To create a simple DIY aluminum insert, fold multiple layers of aluminum foil, ensuring they are quite thick. I disclaim any responsibility regarding the effectiveness of the blocking mechanism; use your own judgment. However, my personal tests demonstrate that even three to four layers of aluminum foil can successfully block common RFID readers. The outside pockets on each side are not RFID-blocked, making them ideal for storing access cards or cash. A step file is included for convenient remixing purposes. If you desire a specific feature, feel free to request it by commenting below. I recommend printing the wallet with a brim to guarantee that it adheres perfectly throughout the print process. Printing at 100% infill with 0.2mm layer heights worked well in my experience. Thingiverse's image preview seems to be incorrectly displaying the aspect ratio of the images, and I am unsure why this issue persists.
