About this model

Hello! This is my adaptation of a 3D NFC keychain in the shape of a pretzel for advertisement/networking needs!Layer 9 has a pause in the Bambulab Slicer for me to insert a round NFC Chip into it. The chip is 22mm in diameter and is adhesive but the space for it is 0.4mm high and 23mm in diameter, so shouldn't have any issues after inserting the adhesive chip and clicking resume.
