Cross monstrance/reliquary

Cross monstrance or reliquary with lockable inner assembly. Total height: 351 mm or 13 4/5 inch (see pictures, ciborium for scale). The largest dimensions while printing in each axis are x: 287 mm, y: 208 mm, z: 119 mm. The symbolism is Jesus-specific: Alpha-Omega, Bread-Wine; INRI, Chi-Rho, IC-XC, Agnus Dei, scroll with seven seals, bronze serpent, Mater Dolorosa, Saint John evangelist, skull of Adam, "Consummatum est!"; seraphim for decoration. It is design in a way, that, taken off the Golgota-scene, it is an independent composition, and could be hanged on the wall. The adapter for the relic inside has to be modified for the specific theca of the relic inside, but I have uploaded a general design.

The parts are: base, main body, 2+2 seraphim, 5 plates with the decoration, 1+2+1 serpent parts, 2 statues, lamb, skull, front rim holding a D=45 mm, v=1 mm glass, backplate, plate for securing the main cross to the base, two pieces for securing the inner adapter (plate and pin) and four pieces for the adapter itself. The cross-securing plate can be further secured to the base with an M4 screw and nut. The connecting dimensions are designed nominally, so some post-processing or gluing might be required, according to your settings. The lamb and the serpent has to be glued. Revell 94 Gold, Revell 93 Copper, Revell 90 Silver and Revell Matt 5 White modeling paints were used. The seven seals were done with real threads and sealwax. Printed with Creality HyperABS.

The adapter is locked in place by the two securing elements, the plate and pin, and those are wrapped around with a thread in a way, that the thread goes around the back of the plate and also through the holes of both the plate and pin. If the thread is sealed with a wax seal or something similar, than the adapter cannot be taken out without residual deformation or damage to one or more parts of the reliquary. See picture.
