This garage door opener holder fits snugly into the gap above the visor, ideally within reach whenever you need to open your door. This print replaces the original metal clip that comes with most garage door openers, especially LiftMaster. You may need to pull back the roof's fabric slightly so that the print can wedge nicely into the gap.

I printed this with 30% infill without supports on my Ender 3 Pro, but you can choose to use more infill for added strength.

I printed with PLA, but PETG will be stronger
