This is a part to substitute the stock magnet door holder on the mUVe3D UltiPro+, Maker and Maker +
This part pushes the magnet closer to the door metal plate so the door sticks better.
You can reuse the screws holding the metal bracket that magnet mounts to. You will need longer screws for fastening the magnet to the 3D printed part. I used 2 x M4 x 20mm
