Frame Bracet Ender-3 Backside Z-Brace

thingiverse

Since I noticed at high speeds that even the Ender3 tends to wobble with the Z tower, something had to be done immediately. Most stiffeners were either unsightly or unusable for the Ender3, prompting me to quickly design some myself. Unlike most front-mounted supports, these brackets are fixed behind the Z tower, minimizing visual disruption while still providing stability and accommodating the power supply. The design ensures threaded rods can reach up to 400mm in length, although slightly longer rods are also feasible. I happened to have a set of 400mm threaded rods from an old ANet A6 lying around, which made this project even easier. To add a professional touch, I recommend encasing the threaded rods with nylon or PET cable hoses and securing the ends with shrink tubing. The result is a much neater appearance.
