Remix of the remix :)
If you do the silicone bed spacer mod (https://sv06.blakadder.com/Upgrades/silicone-mod/), this piece needs to be taller too, otherwise it will sag and not catch the bed anymore.
Pictured with a ~11mm rubber spacer. PETG or better is a must.
If your spacers are taller than 11mm or smaller than 10mm, this will probably not work!
The author remixed this model.
Simply increased the height of the under bed walls by about 2mm
