Creality Ender 3 Heated Bed Strain Relief System

The Creality Ender 3 comes with minimum thought put into the cable management aspect of the machine. This could lead to broken and shorted wires, or cables getting caught on other components of the machine leading to damage or print defects. One of the worst cables for this potential hazard is the heated bed cable. Although the Ender 3 V2 comes with a strain relief bracket, it is not well thought out. It awkwardly sits between the print bed carriage and the bed leveling spring causing the one corner of the bed to be under more force than all other corners. I also found that the Creality bracket can rotate a little bit since it only uses a single screw to secure it to the print carriage. My redesigned component moves the strain relief below the print bed carriage and has an adjustable landing for the cable to ensure the connections to the print bed are under no stress. You can simply make adjustments to the rectangular insert by scaling the part in the Z axis in your slicer. It also uses the leveling screw to mount, with an additional hole for an M3 screw to ensure no rotation is possible. For this screw you will have to use the strain relief part as a drill guide to drill a 1/8" hole in the print carriage for it to pass through. For the heated bed strain relief system you will need: ► (3) M3 x 10 socket or button head screws ► (2) M3 T Nuts ► (1) M3 nylon locking nut This process and system *should* work on a variety of Ender 3 clones such as Voxelab Aquila, Tronxy XY-2, Alfawise U30, Longer LK4, Geeetech A10, BIQU B1, etc.
