MK2 heated bed glass corner holder

The clamps i bought for the glass is too ugly, and it looks unprofessional. spent an hour trying to look for alternative online with no luck, so i have decided to design one myself.

Detail:
heated bed: MK2 from prusa mendel i2 kit(mixshop)
glass: 7 3/4" square x 3mm thick
corner hole diameter: 3mm

one of my concern was that since the part is made of PLA, i was worried that it might warp/deform as it has direct contact to the heated bed. printed a few things and been working great so far.

although the glass thickness is 3mm, i made the counterpart 2.8mm so it can be tightened.

note that this only works if your glass size is exactly the same as mine 7 3/4" or 196.8mm, haven't really looked into the parametric function on this site. But i will do it upon request
