Ender 3 Glass Bed Clips

No real change from procv's model. I just separated them out for printing one at a time because I prefer not to print multiple parts at once if I can avoid it. I find that when I try inevitably one of them loses bed adhesion and ruins the whole thing halfway through, but that likely has more to do with the fact that I don't clean my print surface often enough than anything else.

And, added bonus, this way I can print them on my much faster but much smaller Monoprice Mini Delta (the included gcode is for the Ender 3).

If you don't have my aversion to multiple parts on the print bed that can be ruined if one of them loses adhesion, you should probably just get the original.
