Heatbed Glass Corner Holder Zero Clearance

These Allow for zero clearance to extruder. Designed for units with Auto Bed Leveling implemented. I have included one for reprap with prusa mendel I2 with square glass, one for prusa mendel I2 with slightly rectangle glass (this is what my latest kit came with), and one for use with 0.25 inch glass heatbed such as what I ended up using on my larger printer. Enjoy.
