Stop Peeling Foil Tape Permanently!
If you are lining Andy Huot's incredible Duality LED Track System with HVAC aluminum foil tape to maximize brightness, you have probably noticed that the tape's adhesive struggles to stick cleanly to the vertical, 3D-printed PETG sidewalls over time.
This custom-molded, snap-fit clothes-pin clip solves that exact headache. It snaps securely onto the edge of your tracks, featuring built-in clearance tolerances for the foil tape and a localized internal interference nub that locks into the track's native "neck" indentation.
Be aware, these clips block the use of "skins". I'm mounting my LED tracks out of sight on top of ceiling panels, so these clips were perfect for helping to maximize brightness at the cost of aesthetics.
Features
Zero Light Blockage: Rides cleanly on the upper outer rim, leaving the bottom 10mm/12mm lane completely clear for your FCOB/WS2811 LED strips.
Lead-In Ramps: Features 45-degree entry chamfers at the bottom legs so it glides onto the track smoothly without tearing or wrinkling your foil.
Stress-Relief Geometry: Rounded internal corners prevent the clip from cracking along layer lines when flexing open.
Secure Grip: Features dual internal compression nubs that tightly pinch the track waistline, stopping the clip from sliding around freely.
Installation
Simply smooth your foil tape into the track as best as possible, then press these clips straight down over the top rim every 6 to 8 inches (or anywhere the tape is pulling away). You will feel a satisfying mechanical "click" as they seat into place.
Recommended Print Settings
Material: PETG (Highly recommended over PLA, as PETG provides the long-term spring retention required to keep pressure on the walls without wearing out or warping under mild LED warmth).
Orientation: Print the clip lying flat on its side. Printing it on its side forces the continuous perimeters to wrap around the bend, giving the clip spring strength and stopping it from snapping along layer lines.
Supports: No
Rafts: No
Layer Height: 0.20mm
Perimeters / Wall Loops: 4. 4 perimeters will make the entire clip completely solid perimeters, optimizing spring strength.
