UniTak3D Ender 3 Direct Drive Upgrade Conversion Bracket for Ender 3 V2,Ender 3 Pro and Voxelab Aquila 3D Printer for B-MG&Dual Gear&Bowden Extruder(NOT for Neo Series,Extruder&Hotend NOT Include)

Do all the necessary firmware updates to get the most out of this mechanical upgrade first and foremost. Once you get it installed (not very difficult, just take your time and follow each step, and don't force anything), this gives new life to your Ender 3. Build quality of the conversion bracket is very well done, no burrs anywhere or scratches, very well balanced. Perfect fit to my existing rig with it's original parts and motor. Getting the cables cleaned up and reattached was a breeze. In terms of functionality, I saw massive improvements to my PLA prints as there was no longer any feed problems and I was able to speed up the printer by nearly double without having to heat up the hot end more than an additional 10 degrees. I saw a serious reduction in clogs and there has been no heat transfer that I've witnessed, however, this hasn't been an issue for me so far.

This component is a game changer on my Voxelab Aquila X2. It has made printing more reliable and print quality. It was very easy to install, and I am a 3D printing novice. I do it occasionally and I am far from an expert. I have never modded a printer, and I have had 3 different printers over the past 7 years, just replacing one when I ran into hardware issues (I would rather replace then spend a bunch of time figuring out the issue and buying parts I am not certain will fix the printer) Therefore I was a little concerned to do that with my new Aquila. I went ahead and did it because I was reading how much better it would do with PETG and other flexible. It was so easy to install, and the difference in printing has been very noticeable. Once my bed is level, I don't have to do much tweaking. Everything just prints on even the generic profiles in Prusa Slicer. Rather then spend like $100+ on a whole new hot end and extruder direct drive, just go with this. The value it brings at how cheap it is makes it worth every penny and more. You will not be disappointed!

My WINSINN dual-gear extruder lines up almost perfectly with the hot end as long as I shift the extruder mount plate to the left by 1 screw hole. Totally elegant, no fuss or mods. I would give it a 4 star if this weren't so negligible to me: The spanner that came with this product is not sized correctly for the hex-head bolt they provided to replace the tensioner bolt, it's the same size as the one that comes with the Ender 3 (I actually like it better though cuz it's a bit thicker). I ended up just bolting the tensioner bolt in before putting the extruder on the plate, it took a little thinking to get the order right but it works fine (but I had to leave out the little corner bolt under it, not a problem). The tensioner bolt is inaccessible unless I disassemble it, but thankfully I don't think I'll ever have to adjust mine since it uses that thick yellow spring. One thing in particular I like about this mount is that I can view the gears turning easily as it prints, which is sometimes vital to diagnosing printing issues. It also does not clash on the frame like some of the more weight-balanced printed mounts would (requiring a spacer on the carriage to hit the endstop earlier, thus reducing effective bed X dimensions by ~30mm). I don't observe any leaning-forward or odd vibrations at all even without overtightening the carriage's eccentric nut. Oh also the belt holders are exactly the same spacing as my stock Creality ones. I also was happy that it comes with its own rollers, so I can repurpose my old X rollers for my Y axis since those are much more worn down by now. This was definitely a great purchase.

Pretty easy install, just replacing the whole plate and have to put the hot end on. It fit my Voxelab Aquila really nice. Only issue I have is if you’re using a CR Touch for bed leveling all the brackets on that plate hit the X axis limit switch and cause the shroud to crash. That can be solved with some printing so no biggie. As for the metal and everything it was pretty nice and everything felt pretty solid. I have notice some improvement with prints as I was having issues before with my Bowden pulling out but after going direct drive much easier. Everything lines up well and I haven’t noticed any heat sink yet so solid purchase. About intermediate level install but once dialed in the settings it works great. Change your retraction rate on your machine too by the way. On my Aquila I went .5mm retraction and 40mm retraction speed

Installed on Ender 3 v2. Initial impressions are that the materials/finish are of good quality. Anodized coating matches the Ender frame color - looks factory/stock. Install instructions are good, but just too small. Relied on the video recommended in the instructions for clear path to install. I had an issue in which one of the four feeder motor mount screws could not be accessed. You have to install a replacement hex-head bolt on the feeder, as the stock screw won't fit. I could not get a hex head wrench into the motor mount screw no matter how many times I tried. See the circle in my photos. I went with three motor mount screws, made sure they were tight, and no issue so far. + Great component quality + Complete kit, including wrenches, zip-ties, velco ties, etc + Instructions included (be sure to reference the YouTube video mentioned in the instructions) + Excellent direct drive solution, while keeping factory stock motor/feeded/hot end - Instruction print size is small (example - the illustration of screw locations is hard to see) - Feed tension bolt interferes with access for one of the motor mount screws (in my case) Highly recommend this kit.

Simply put, the design could use a little massaging. The bolts that hold the upper bracket to the lower do not allow you any room for an allen wrench to set the depth of the tension bolt on the extruder. . I used one of their dual gear extruders and didn't go 100% with their documenttaion as it didn't work. Do NOT fully seat the tension bolt, just have it in there deep enough you can get the allen key in to tighten the mounting bolt in the corner, THEN using needle nose pliers CAREFULLY adjust the tension bolt by grabbing the bolt head (screw head whatever). ***UPDATE*** After some extensive use I am finding issues with the extruder. Simply put the extruder bolt that holds the gear in likes to tighten itself over time causing the gear to stop turning and extrusion to stop, well extruding. Considering the cost and effort of putting this together, along with a Spider V3 hot end, if I had it to do over again. I would have simply gone full on out and went with a Creality Sprite Pro Kit. Everything is designed to work together, nothing extra to build, just poke it in, load supporting firmware, do your calibrations and be happy with the results. Second issue, yes this works on a Voxelab Aquila, NO it does not work with an Aquila with the 3D printed BL Touch mounts or associated fan shrouds with BL Touch mounts. Solution to this problem, 3D print the eB Fan shroud for Ender 3 / CR10. found on thingiverse, and use the Ender 3 BL Touch / 3D Touch mount kit. Bolts right up and fits tight. The Aquila fan shroud screw and 1 additional screw will secure the mount to the bracket / X axis carriage no sweat. Once installed and combined with a BL Touch / 3D Touch bed leveling sensor and dual Z axis kit, this takes the Aquila and Ender 3 to an entirely new level... Like a MUCH more expensive printer. Just be paitent with the installation process.

Bought this to upgrade my Ender 3v2 and couldn't afford too grab the sprite pro. Has performed great, much less stringing and my prints have improved significantly, especially when it comes to higher detail models. If you are looking to upgrade on a budget and don't mind a little more tinkering, this kit is well worth it.

After installing direct drive I wouldn't want to go back to the stock Ender 3 setup. It works very well, I have almost no skipping. Make sure the cables don't cause the gandry to bash into the right hand rail. I also use custom firmware and just limited the boundaries to accommodate the direct drive cables safely.
