Summary

I finally ran out of Robo3D's bed adhesion tape so I ordered a piece of Borosilicate glass from Amazon and designed these clips to hold the glass in place. Works great and holds it well.

The one I order is listed below. It has a 130x130x3 mm footprint.

P.s. I printed the 4 clips with PLA but it's probably preferrable to print it in ABS or something more flexible if you're able to.

Also, due to the print bed being a detachable two piece design, it doesn't work too well with having clips attached to the plastic piece of the bed so I used 4 #8 nuts as spaces on the underside of the plastic piece of the build plate and hot glue them in place. It gave me a little bit more clearance to attach the clips.
