Ender-3 print bed insulation holder (revision 2)

A thing to keep a insulation mat pressed against the heated print bed for quicker heating.

The insulation I have bought (link below) is very fragile, maybe it's bad quality, anyway trying to stretch it between the screws just makes it rip. So I made this thing to hold it in place.
