Let's take a closer look at the Haldis 3D Black Knight Ender-3 V2/Ender-3 Pro 3D Printer Upgraded Timing Belt & Screws Kit.
This kit is designed and developed by the HS team and it's an excellent choice for those looking to upgrade their Ender 3 printer.

One of the most exceptional features of this upgrade kit is that more than 90 percent of the parts are processed by CNC making it incredibly compatible with the Ender3/Ender3 V2 /Ender3 Pro. The upgrade package provides a reserved interface for upgrading Double Z, which is a great added feature. The rails are of high quality, with smooth movement and no loose parts, providing much-needed rigidity to the printer. The included instructions are clear and easy to follow making assembly a breeze.

The benefits outweigh the drawbacks with this kit. One potential disadvantage is that the included belt might be a bit short for some users but this can be easily remedied by purchasing a longer one. Another minor issue is that some users wished that there were more mounting points on the nozzle kit connection plate. However, overall, the quality of the parts is excellent, and the kit is well-designed and thought out.
