Wuben G5 Extended Magnet Base Attachment

I made this extended magnetic base for the Wuben G5. I absolutely love this flashlight with my only qualm being that it doesn't stay stuck to metal when placed in the horizontal position. I designed and printed this base plate with two 15 mm x 2 mm magnets embedded in the print.

This 100% solves the problem I encountered but I want to make something that is more accessible for those that might not have the knowledge to embed magnets or pause a print. I was thinking about making a base plate that just extends the surface area that is coming in contact with whatever you're sticking the flashlight on to make the light less likely to fall off.

As always, my comments are open and I would love to hear any feedback or questions that you might have about this design or print.
