This original support that I designed adds stability to the upright section of the Ender 3 series of printers - it is placed on the far right side of the base frame up against the upright pillar.

It can be used as a single support, or two of them can be printed and used side by side, to create even greater stability

You will need 4 x 10mm or 12mm M5 button head bolts - some M5 T-Head or Hammer-Head nuts to attach the bracket to the Printers Frame.
