Assembled Pieces

This exercise is part of the E3D+VET program's 30 exercises developed during the Erasmus+ program, which focuses on immersion in 3D printing for VET centres (https://www.e3dplusvet.eu/). The assembled model consists of two parts printed separately. This exercise introduces three types, all featuring a repeating pattern that creates an inseparable joinery once assembled. These models are based on the lock and key concept, with clearance allowing smooth sliding between the two parts. Dovetail: The basic geometry of this model is a cube made up of two halves. One half has two protrusions resembling classic dovetails in carpentry, distorted to fit. The other half features two cavities also shaped like dovetails. These halves connect in such a way that loosening requires pushing them apart in the right directions, with only one possible axis for movement - forwards and backwards along an axis parallel to the cavities' orientation. Pentagon: This model is a variation of Dovetail, featuring two pentagonal halves following the same construction principles. Triangular Dovetail: The two halves form an equilateral triangle that can only be loosened by rotating it around the z-axis and then pulling apart. The pattern intersects with the triangular body, creating this unique connection.
