Roman Arc
thingiverse
Roman arches are an ingenious architectural design as they don't require concrete or cement to hold them together. The weight of the top, or key stone, keeps the structure stable. To construct one, scaffolding is used for laying the curved stones before inserting the key stone. Care must be taken to accommodate lateral forces and prevent toppling by wedging the columns into the base plate. Once printed and assembled, please share your experience with me.
