3DRC have introduced their new front belt tensioner for the Serpent Project 4X touring car. The design allows to run the car with decreased belt tension for a more efficient drivetrain. 3-D-printed for a low weight and good stability the part weighs in at only 2g. Not included is the necessary hardware in the form of two M3x10mm button head screws, one M3x6mm button head screw and two 3x6x2.5mm ball bearings. The belt tensioner is easy to install and allow for a wide range of belt tension adjustments. The part is available through 3DRC’s Shapeways store or select hobby shops.
