spotlight size adapter

This is a very simple design i made to fit new LED spotlights in my kitchen ceiling. The old spotlights were bigger and i needed something that looked nice and made it possible to fit the smaller spotlights in the larger hole.
This is designed in OpenSCAD and the size's are defined in the module call, so they are easily adaptable to your needs.

The standing ring serves three purposes:

• it prevents the surface from bending
• it centers the adaptor in the hole
• it prevents draft from the ceiling into the kitchen

Allthough it's dead simple this is for me one of the great joys of having a 3D-printer. There is something you need fixing, you imagine the solution, design it, print it, and presto, it's fixed :-)
