Add a bit of mystery to your next Gift Card gift. Simply insert a Gift Card inside this box during printing and once complete, the card is encased in a thin shell. Leave it to the recipient to figure out how to get the card out. This is intended to be a single use print, with opening involving destroying it in some way.The inside of the vault is hollow, with 1mm sides all around, and is large enough to easily accommodate a standard gift card (possibly two) . The purpose of the side tower is to have a place to pause the print that is offset enough to get the extruder out of the way of the vault. Print with the vault standing upright, with a long edge on the printbed. At approximately 90% completion, pause the print while the extruder is over the side tower. Insert the gift card and then complete the print to seal in the card. Vaults with "Question marks", "Happy Birthday", and "Merry Christmas" are provided. Also included is a blank vault awaiting personalization. Versions without the 'tower' are provided in case you have a better way to pause the print when inserting the card.
