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

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.

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.

It’s metal

I purchased these motor mounts with the expectation that they would help align my z-axis motors evenly. However, I was disappointed to find that there was a noticeable amount of play in the mounts, which made it impossible to achieve the level of precision I needed. As a result, I had to return the product.While I appreciate the effort put into designing these mounts, I cannot recommend them for those seeking to achieve highly precise alignments. I suggest that the manufacturer explore ways to minimize the amount of play in the mounts, as this would greatly improve their effectiveness.Overall, while these motor mounts did not meet my needs, I am optimistic that the manufacturer will continue to improve upon their design and produce a more suitable product in the future.

added this to my build list because i didnt want to trust my new printers alognment with a small plastic block.fit was great and easy to install.

It's a nice to have but it doesn't do anything the stock mount don't

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

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.
