Introducing the Revo Hemera XS Coldside Kits available in direct drive (12V or 24V) or bowden kit types.
Features
- Shorter and lighter. Hemera XS is 92g lighter and 11mm shorter than classic Hemera. A custom stepper motor means it can move faster on your 3D printer’s motion system with less inertia than classic Hemera, reducing print artefacts such as ghosting. Its compact size also means it occupies less space inside your 3D printer’s build volume – useful for smaller 3D printers.
- Capable with wide range of 3D printing filaments. Enjoy excellent performance with all 3D printing materials, particularly challenging materials like flexibles and abrasives. Enhanced extrusion and retraction control means you can 3D print soft flexibles with a shore hardness as low as 75A!
- Backwards compatible. The heatsink geometry for Hemera XS accepts Revo Nozzles as well as V6 nozzles with a Hemera HeatBreak (sold separately).
- All the force you need. Hemera XS has all the extrusion force you need to drive the entire E3D ecosystem, including high flow HotEnds like SuperVolcano and Revo High Flow Nozzles.
- Less likely to strip filament. In the event of a jam, the filament drive mechanism for Hemera XS will stall instead of stripping filament, making it easier to recover and get 3D printing again.
- Better safety. Power reduces to the Revo HeaterCore as it gets hotter, thanks to built-in PTC behaviour. This gives you greater protection against hazards caused by thermal runaways.
- T-slot flat mounting. Our custom mounting system means a range of accessories can be mounted on this extrusion system, such as bed levelling probes, expansion boards, and more!
Pair with your perfect Hotside
Pair your Hemera XS Extruder with one of our carefully curated Hotside packs to ensure your printing needs are met, straight out of the box.

- Starter - Ideal for users printing at standard speeds with PLA, PETG and ASA

Great!
This dog ball thrower is sturdy and easy to use, especially for longer throwing sessions. The length helps keep hands clean, and it launches balls smoothly without much effort. The foldable design makes it easier to store or bring along.
After plenty of use, it’s held up well and hasn’t cracked or loosened. Our German shepherd pups are LOVING the further distance throws! It’s made fetch easier on arms and shoulders, and it works reliably.

My dog is obsessed with this
My dog absolutely loves this ball launcher. The second it comes out he knows it is time to play and gets so excited. It makes throwing the ball much easier and sends it way farther than I can throw on my own, which is perfect for burning off energy at the park.
I really like that I do not have to pick up a slobbery ball with my hands. Scooping it up is quick and easy and keeps my hands clean. The handle is comfortable to hold and does not slip, even during longer play sessions.
The foldable design is a nice bonus and makes it easy to toss in the car or store when we are done. Overall this has been a big hit in our house and has made fetch even more fun for both of us.

Just like a regular Chuckit launcher but easily folds in half if needed
Our dog loves chasing balls! And, if we're out in the woods, he'll chase the ball and bring it back and say "throw it again"...again and again. Well, he doesn't actually "say:" anything, but he just loves to fetch and retrieve. With this ball launcher, it's easy to pick up the slimy ball and throw it. We have Chuckit launchers that are 27 inches and they are awesome. They are long enough that I don't even have to bend down to pick them up to throw again. With this item, it's 25 inches extended, but that's good enough. Same thing as the Chuckit launcher, but you can easily bend it in half if needed then open it up and lock it in place to have a reasonable facsimile of a regular launcher. It comes with a tennis ball-like ball. Get some Chuckit balls for it. Much better than tennis balls.

Best thing ever!
Size: Mini
I had no idea how my dog would react to this. She would play fetch but she seemed to get bored. This Chuck It is probably my dog's favorite toy. I love it because I can actually get the ball a lot further to get her running more. And I love how easy it makes picking up the ball. All in all, this is so worth the little bit of money it is. My dog gets so excited when I ask her if she wants to play with her Chuck It. I'd buy this again and again. This thing saves my arm and back, and my dog gets some serious exercise. Winner winner. I also love how this one folds. I can fit it anywhere to take it along. Really I simply can't say enough good things about this little ball flinger. It's also my favorite thing to play with my pup.

Great for Big and Small Dogs
Size: Mini
This launcher is on the smaller side, but it gets the job done! It’s perfect for small dogs and still throws far enough to tire out my golden retriever at the dog park. I thought it might fold while throwing, but it locks in place and holds straight really well. The foldable design makes it easy to carry in a small bag or leave in the car for spontaneous play. Lightweight, compact, and surprisingly sturdy, definitely a must-have if want to have a extra to leave in you car .
