Fix Corner Warp

Hello!

My door panel of the VC4 has it's upper corners bowing out when the enclosure temperature exceeds 40 degress Celcius, creating quite a gap.

To solve this issue, I came up with this small magnet holder that inserts into the slot of the extrusion. That magnet pulls on the M3 screw and nut that are inserted into the two small holes that need to be drilled into the corners of the panel. 

With the constant pull, the corners no longer bow out, fixing the issue.

Part required:

• printed magnet holed;
• 10mm diameter x 5 mm high magnet, the same as the others provided by RatRig when buying a kit from them;
• M3x6 bolt;
• M3 nut;
• M3x1 washer (more metal for the magnet to pull)

Mounting steps:

• insert the magnet into the printed magnet holder;
• slide the magnet holder into the extrusion slot, it has to be snug in order to stay in place;
• place the door in the default position on the printer;
• mark the middle of the magnet on the panel corners;
• remove the panel and drill out the 3 mm holes;
• insert the bolt, washer and nut and tighten them;
• replace the door, check if the washer is aligned with the magnet and does not interfer with the extrusion, move the washer if needed
