These are a couple of hooks that mount in the vents over the wheel in the trunk of the Hyundai Tucson nx4 to hold a small fire extinguisher. In addition to the hooks some 20mm wide velcro is required.

I printed them in petg (will change to asa if petg doesn't behave) with the following settings:

• nozzle: 0.4

• layer height: 0.2

• wall loops: 5 (this is important)

• top/bottom layers: 3

• sparse infill: 30% gyroid

• supports: none
