These are simple clips for holding glass onto the build plate. (The flat section goes on the top.) I didn't like using binder clips and wanted something lower profile. For larger or smaller print beds, you can re-slice the STL file to whatever size you require.

I did modify the original file I uploaded. I found that the plastic eventually stretched out a bit and started to slip, so I narrowed the gap a bit.
