This adapter is designed to mount an IKEA dioder led lamp into an halogen spot light hole of a IKEA closet.
The adapter fits into a 66 mm hole (odd IKEA spot hole diameter), and has a 80 mm 1,5mm thin bezel.
The design has some slack for the dioder led lamp to allow for 3D print tolerances (hole=52 mm).
I have included the 123d design files so one can modify this design to fit ones needs, and adapt it for larger or smaller holes.
When using natural PLA some light of the LED partly illuminates the bezel.
