Low Profile Recessed Can Light Trim Ring Goof Ring

Full Description / Project Story

This project was created while upgrading the lighting in my house, which was remodeled in the mid-2000s and outfitted with over 40 identical recessed can lights.

During the LED retrofit process, several of the original trim rings cracked, and many others showed noticeable yellowing from long-term UV exposure. I initially assumed replacement trim rings would be easy to find online, but quickly discovered that:

• Matching replacements were unavailable
• Off-the-shelf goof rings were either too wide, had the wrong profile, or didn’t match the original aesthetic
• Custom-manufactured trim rings would cost $15+ per piece, which quickly becomes expensive when replacing dozens of fixtures

To solve this, I designed a low-profile, minimal-coverage trim ring that closely matches the original look, provides clean edge coverage, and prints efficiently.

The result is a simple, durable replacement ring that:

• Preserves the original visual profile
• Covers drywall cut imperfections
• Restores uniform appearance across large lighting installations
• Costs only a few cents per ring to print
• Brim optional for ASA/ABS to prevent edge lift.
• Supports not required.
