Couldn't find a simple bracket to fit under cabinet led lights like the ones I had so I designed my own. Printed using PETG for extra flexibility on the clamp. Might work with PLA too.
The light bars can be mounted with M3x12 counter sunk screws and nuts or using self taping screws. The ones I used cave with metal springy brackets that clamp onto the led light body.
