Upon transforming Magic Square Trailbreaker I noticed how loose the waist piece was. I took to my 3D modeling software to create a small bracket that plugs into slots under the from bumper of the car. It is easily removable for Transformation. The file can be downloaded from Thingiverse and takes about 5 minutes to print. Magic Square MS-B09 Trailblazer Waist Bracket by Trikeboy
