From the maker:
It is with a mixture of pride and humility that I am now ready to announce my first puzzle to the community, so please all meet MailCall!. Below I will give some more information on the puzzle. Since some people prefer a complete surprise I will spoilertag some information, but even reading everything will not give you any information that can be used to solve the puzzle. MailCall! Is a 3D-printed sequential discovery puzzle weighing a little over 600 grams and measuring 10 by 10 by 16 cm. It is made of PLA and 63 pieces of hardware.
