Ender 3 Strain Relief for Stock Hotend Assembly
thingiverse
I needed a simple strain relief solution for my Ender 3 that utilized the existing screws on top of the stock part fan. Additionally, it slides onto the back plate of the hotend for extra support. Note that the wires from the stock part fan have a notch to pass through. Pictures are of version one of my design, version two that I uploaded moved the seat for the bowden tube back 1mm to better align with the hotend and also widened the fork in the screw points to hopefully prevent or reduce cracking at installation.
