CR-10/Ender 3 Wedge Jack

thingiverse

UPDATE: Version 2.0 August 19,2018 Long overdue update with some requested features. V2 requires one M3 screw and one M3 nut. Overall length is now reduced to 42mm (should fit the Ender 3). Standard height is 13.5mm before extension. If you need increased height, WJ_Lift_Ext_V2 will extend the height by default by 5mm. Most parts don't require support, but part WJ_Wedge_V2 may benefit from added support if needed. The hex screw can now extend and retract the wedge (counterclockwise raises, clockwise lowers). Feel free to request changes to fit your needs. UPDATE: Version 1.5 August 16,2017 Minor modifications were made. The jack was found to be tight when inserted, so it was modified to be another 2mm shorter in height and 5mm shorter in length. Voila! No bed sag! The CR-10's build plate had a sag in the middle, just enough to throw off the bed leveling process. The Jailcee W-Jack design is loved, but some modifications were needed. 1. Now uses an M3 screw and nuts. 2. Total height of the jack reduced by 1.5mm 3. Built-in tracks for less possibility of side slip. Parts required: 1@M3x30mm (shorter may work) 2@M3 nuts NOTE: Be very cautious of the electrical work in the center of the build plate. The wedge jack should fit forward of that area comfortably. Please see the build photo for placement.
