V-Slot M3 Nut Insert (T-Slot Adapter)

This is a 3D printable T-slot nut adapter designed for 2020 V-slot aluminum extrusion profiles.
It fits tightly into the profile’s groove and includes a press-fit cavity for a standard M3 hex nut. Once inserted, it allows you to screw in M3 bolts directly into the slot for mounting brackets, panels, or accessories.

Unlike metal T-nuts, this version is lightweight, customizable, and printable in bulk — perfect for prototyping or non-structural assemblies.
