About this 3D model

During the installation of the 2020 profile frame, the ball nut was missing, and there were some ordinary nuts on hand, so I designed an M5 hex nut to T-nut adapter. Using a standard M5 hex nut with a thickness of 3.1-3.3mm nested inside, it works well. The size is accurately positioned and does not slide. The only drawback is that it must be installed in advance.
