I originally designed this vault because out of all the freely available vaults I've found, none of them combined all of the features I was looking for.
The holes are intended to be fitted with 6x3mm magnets and I've added a raised edge for alignment so that it's more resistant to being opened unintentionally when stored in a backpack. The default scale will fit both halves side-by-side on a single BambuLabs A1 Mini plate, but you can adjust the equation variables in the included SolidPart file to any size your heart desires.
Also included in the SLDPRT (2023SP5) file are configurations for rectangular and circular versions of the part if you wish to deviate from the bestagon for some unknown reason.
The author marked this model as their own original creation.
