1980's Yamaha rectangular LED headlight adapter

This is an adapter I made to fit the common 4X6 rectangular headlight from Amazon or EBay to fit mid to late 1980's Yamaha bikes with the square headlight. It should fit almost any 1980's Yamaha bike. The bike I installed was a 1986 Radian 600.

Most of these LED headlights you see have the same profile. The screws in the back are 4mm. The holes should line up perfectly with them.

I added the STL as well as the FreeCad model source where the adapter was designed.

No supports should be needed for this print.
