From 3DRC :
The perfect option to calm down the front belt of Serpent Project 4X. Possible to adjust a lower belt tension for more efficient drivetrain. The belt tensioner weights only 2 grams. Not included is the hardware. 2x M3x10mm button head screws, 1x M3x6mm button head screw and 2x 3x6x2.5mm ball bearings are needed.
The belt tensioner is easy to install and has a wide range of belt tension adjustment.
Available through 3DRC´s Shapeways Store or selected hobby shops.
