See the complete expansion list

To match the pictured expansion: print 16 pieces in 14 print jobs - that is the build itself. Because this build uses magnetic closure, it also needs 4 more printed pieces and 4 bought items; turn that option off and those go away. Optional extras add 8 pieces the build works without. Most of it is simply more of what you have already made.
