 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?
