Please proceed with caution when you assemble those parts. The installer should measure the necessary length with the caliper and not put the parts in and out multiple times - this could lead to damaging small details. After measuring the parts should be cut to the correct length and installed only once - then they will not break and will keep the connections well.

P.S. Also avoid freezing the parts or it is very cold in your room. Please heat them a bit. If the material is cold or frozen it becomes very brittle.
