Probably the main detractor for resin casting in this particular case is going to be how the parts are designed. Unless a part was designed to be cast, it's probably not going to be cast.
they were designed to be cast, although some of the parts would require a very unusual pair of molds, where assembly and disassembly would need *two* moves (first sideways and **THEN** upwards) to split them apart.
the idea was to have a generic "block" into which mold parts with fixed outer dimensions were placed (held together), with mold parts having three sides *MEETING AT ONE SPECIFIC CORNER* and the other mold part having three sides meeting AT THE DIRECT OPPOSITE CORNER instead of the more traditional "top and bottom" mold parts.
but the molding isn't the main concern, it's the materials strength. does resin have enough strength and stiffness to not fall apart if it is used to span a distance of 330mm?
