Kossel Mini Borosilicate Glass Print Surface Top Clip

I found that if the action on the auto Z leveling probe isn't smooth, then the bed won't stay in place when it gets to an edge!
This is a simple keeper that stacks on the rounded print bed platform.
I've printed this and fixed the scad so the part is customizable.

You can now customize a second lip to press against the side of the print bed as well so you have horizontal and vertical pressure on the build platform.
