AM alphamount TV Floor Stand for 13-43 inch Flat/Curved TVs up to 44 lbs, 8 Level Height Adjustable Monitor Floor TV Stand with VESA 200x200, Portable TV Mount Stand for Living Room, Bedroom, Office

This is what I used, but I also heavy modified the stand so that it was shorter. And then 3D printed brackets for the PC and Battery backup. I should have the brackets uploaded to Bambu's site later.
