This is the Prusa XL series: Front Antivibration/support 3030 PETG extrusion by Surfalex2000 with Prusa XL graphics added to the Front of the support (prints on the TOP, installs towards front). I had already resized it by 100.41% for PETg according to the source model suggestion.
The author remixed this model.
Added Original Prusa XL graphics for dual color print.
