This model can be tricky to print and assemble because of the fragile corners of the “shell” piece. At 100% this model will be fairly large. It can be printed as small as 50% (pictured) but it is more difficult to build at that size without breaking the shell corners. The sharp edges of the side insert pieces may need to be sanded or trimmed down in order to avoid breaking the shell corners. The shell piece should be printed laying flat with the outer face up to maximize the strength of the fragile corners. Organic supports are highly recommended. The side inserts hold the triangular inserts firmly in place, and the rest of the joints can be hot glued or CA glued.
