About this 3D model
I am happy to share this simple glass raiser composed of only four corners: it does not require connectors for assembly, it is very easy to print, install and remove. You will find two printing profiles for this riser: the main one is to make it in two colors (as in the photo), the other is to print the corners in a single color. There is also a third profile with an optional element to be positioned centrally, made specifically for a user: it is not an essential element, the four corners are enough. If instead you prefer a complete and more solid structure , see if this can be useful to you:
