Reducer to the size of 14.15 x 6.5 alu profile (LED Light Bar Pusa i3 MK3)

I couldn't get proper profile. I created a small reducer for profile 14.15x6.5 mm. The reducer must be inserted into each end of the aluminum profile holder before soldering the cable to the strap. Or it is possible to slide the reducer onto the aluminum profile and only then solder the cables. Sorry for low quality, it is exported from free version Shapr3D. But it is working ;-)
