Cat Ear Headphone Upgrade – Customizable with Magnetic Lids & Light Slot

This is a fun and stylish cat ear accessory designed to enhance your headphones! The model includes interchangeable magnetic lids and an internal compartment that can house a small wireless RGB light—or simply serve as a discreet storage space for tiny items.

The design consists of multiple parts, allowing for easy customization with your favorite filament colors. This lets you tailor the look to match your personal style.

🔧 Assembly Note:

The rear plate's "slot" area is meant primarily as a visual alignment aid for centering and symmetry—it’s not designed for a friction-fit. The alignment pins on the backplate, however, should align and fit into place. I encountered no issues when using PLA, but PETG (especially clear variants) may lead to tolerance inconsistencies. I reccomend clear silicon or clear epoxy glue for assembly

To achieve a clean, minimal appearance, I designed the ears to be mounted using Velcro or magnetic tape. Although I added an optional "mount" version with hooks (based on a friend’s request), I don’t recommend it due to its inferior stability and aesthetics.

💡 Tip:

I initially tried using low-quality magnetic tape, which performed poorly. Switching to Velcro gave excellent results—secure hold, easy removal, and no visible mess.
