About this 3D model

After upgrading the direct drive extruder on a CR10, it was found the bed was too low. The springs did not allow a tight connection with the adjusters and would begin to loosen easily. The bed spring extenders allow for the bed to be raised higher compared to the stock spring capabilities and maintains a tight connection. Four different sizes of the extenders are available: 4mm, 6mm, 8mm, and 10mm.
