Had some trouble using these lights:
As the magnet would be too far from the light to properly turn it off. Especially using the provided hook and loop. This tilts it so that for one thing it's better aimed, 2ndly make it's protrude into the frame so it will be closer to the magnet and more reliable. Also makes it a lot easier than the velcro to remove and fill batteries.
I printed using PLA+ with the small flat part of the back, bedside down. That way I could print it with no support material. Though if you want it strong you should print face down, (or the way the stl is oriented by default) with support material. But at the 45 degree angle I printed at it seems strong enough for me, only time will tell.
