A leg extension for Hercules Mini Guitar Stand GS402B/W. I use two of them to effectively drop the left hand side and fit my guitar's shape. In addition I also added some extra padding (pipe insulation) to help protect the guitar as my RD is quite heavy. I printed mine in PET-G.
To install, pull off the rubber foot from the guitar stand, and push it to the leg extension's plain end, then push the leg extension into the guitar stand leg as per the pictures.
