This is another member of the evergrowing void-family: Classical puzzles of which the core was seemingly removed.
In this case a Pyraminx was implemented with an empty space instead of the classical core. The size is identical to Mefferts Pyraminx with sharp tips.
In the first version the inventor locked the mechanism to prevent it from being taken apart. In 2017 he designed another version which can be disassembled and named it "Gift Void Pyraminx". Please refer to image 7.

Thank you to the following people for their assistance in helping collect the information on this page: Andreas Nortmann, Lawrence Cuthbert.
