Upgrade Metal Ender 3 Z Axis Stepper Motor Fixed Mount Installation Bracket for Ender3 V2 Ender3 Pro CR10 CR-10 V2 V3 CR10S PRO Z-Axis with 2040 Aluminum Profiles 3D Printer

These brackets are far better than the cheap plastic mounts that come with the Ender 3 and other Creality printers, and are an inexpensive upgrade. I like that they attach to all four mounting points of the stepper motor, and not just along one edge. They come with both screws and T-nuts for mounting in the extruded channel of the frame, and longer screws for mounting directly to the frame, although on my Ender 3 V2, I found the holes in the frame ever so slightly misaligned with the bracket. By default the Ender 3 only has 1 Z-axis stepper anyway so I just used the T-nuts on both sides and they worked perfect! Install was very simple. I am very satisfied. This, along with aluminum upper screw brackets and bearings made my dual Z-axis screws very square and solid. Zero play in the Z-axis now. I think this is one of many essential Creality printer upgrades and definitely recommend them! Too bad Creality didn't use metal brackets to begin with. But these fix that problem fantastically.

The Polisi3D mounts are extremely high quality, easy to install and add much needed rigidity to the printer's Z Axis. The printer's existing hardware will work so no need to use the included screws if you don't want to. The stock Z motor mounts are made of plastic and while they are sturdy they cannot compare to these. These motor mounts eliminate all flex in the z steppers during printing which results in cleaner and higher quality prints especially when printing at 250-300 mm/s. The plastic mounts also cause an odd vibration sound during Z moved that even with stepper dampers just couldn't resolve until I replaced them with the aluminum mounts. Do yourself a favor and printout some .8mm NEMA17 sound dampers (found on Thingaverse) from TPU and install at the same time. This will all but eliminate stepper noise on each axis you use them on making for a significantly quieter printer. End of the day, these are an inexpensive but worthwhile upgrade for virtually any bed slinger printer that utilizes this type of mounting system for the Z steppers.

I love this thing. It was super easy to install and functions far better than the ones I tried to 3d print. It made my zrod alignment so much better and fixed some binding issues I had. This thing fits tight and you will have to move your z stop but it works great, was super cheap, and built perfectly.

Did the upgrade before i had problems. Feels a bit pricie for 1. did a video on it. Bolts right up. and you dont have to slide in in the track

Fit my Anycubic Vyper and was 5mm shorter than the stock mount letting me fit bigger stepper motors. Great deal for the price. Metal doesn’t feel cheap and the included hardware is good. No instructions are provided but installation is pretty obvious.

The small plastic mounts that came with my Ender 3 V2. Had the lead screw tilted towards the gantry, almost touching. Shimming them with aluminum foil didn't help. These mounts are all aluminum after installing them the lead screw is perfect! I highly recommend this product!

These worked great for the beast that I am building. 1200mm x 1200mm x600mm

Recently did some upgrades to my Ender 3 S1 pro and found my original plastic Z stepper mounts were all cracked up barely hanging on......got 2 of these to switch them out for the last time. Fit perfect and supplied hardware was a plus.

Der Motor sitzt damit bombenfest.

Klar sollte das Ding aus Metall sein.. Plaste is da völlig unangebracht. Hält den Motor sehr gut, braucht nie wieder gelöst zu werden. Der obere Abschluß (mit Lager) sollte dann von den Abständen her passend gewählt werden. Auch hier gilt, besser Metall als Plaste. Allein der Preis stößt etwas ab...

Without the full set of screws and T nuts you cant really use the bracket which seems to be OK. I returned the product and got refunded.
