This is a remodeled version of the bottom lid for the Preform (PET) Cryptex Lock by djwhouse which allows to insert a NFC sticker.
I loved the original idea of the PET cryptex and wanted to add a NFC tag which holds the combination of the lock.
Pause the print at 1.4 mm and insert the NFC sticker. The space for the sticker has a diameter of 39 mm and a height of 0.4 mm.
