Gothic monstrance/reliquary

Gothic monstrance or reliquary with lockable inner assembly. Total height: 775 mm or 30 1/2 inch, if printed in 100% (see pictures, ciborium for scale). The largest dimensions while printing in each axis are x: 250 mm, y: 290 mm, z: 259 mm. According to the relic inside, the two empty spaces on the lower part of the main body can be decorated freely, just as the statues can be chosen freely. I uploaded here the final .stl files of the three statues I used and modified, with their original sources below. Obviously, the adapter has to be modified for the specific theca of the relic inside, but I have uploaded a general design; it works by grabbing the theca at its front rim.

The parts are: base, main body, three towers (each two pieces + pins), front rim holding a D=45 mm, v=1 mm glass, backplate, two pieces for securing the inner adapter (plate and pin) and four pieces for the adapter itself. The connecting dimensions are designed nominal, so post-processing is required, especially wit
