About this 3D model

Two little tools to see if your Ultimaker XY guiding rods timing belts are correctly aligned according to the 'sliding blocks' The optimum is that the timing belt of the X -rod has no Y component, so the 2 pullies and the 'sliding block' must be in the same Y-plane. This should reduce mechanical stress in the system and gives a more balanced load for the belts/pulleys. It can be difficult to see if the pulley is mounted straight above/below the rods. The tool has a complexity/added value ratio of 1 (It can boost your Ultimaker performance with at least 0.000005%)
