Wootoff Light Magnetic Base

Base for a classic Wootoff light that allows you to add a magnet for magnetic mounting.
The magnet I use is 12mm x 2.66mm. You should be able to use up to 3.25mm thickness in this.
The second model (wootoff_halfinch.stl) is a little larger and should work with a 1/2" x 1/8" ring magnet, with a #4 screw clearance hole.
You will have to add a blob of glue to the top of the post in the center of the magnet to get it to stay. I'll use some ABS paste.

Third and Fourth models (with _d appended, for disc) are the first two without the shaft for the hole in the magnet.

I think you should use at least an N42 magnet to get these to stick.
