Are you looking for a Bondtech Prusa MK3S Mosquito Upgrade in Australia?

This Upgrade Kit does not include the gears (already supplied by Prusa).

This Upgrade Kit requires extra parts to install (X-Carriage Kit).
You can buy it from us or you can download the STLs and 3D print them.

 Perfectly designed for the Slice Engineering Mosquito/Mosquito Magnum

Upgrade Your Extruder

Upgrade your extruder to a Bondtech Mini Geared with higher gear ratio – 3:1 – that allows for extra push force and higher resolution.

Print Faster Or With Higher Quality

Use a lightweight extruder that will allow your 3D printer to print faster or to achieve better surface quality.

Reduce 3D Printing Issues

Decrease the risk of heat creep to avoid clogs and improve filament feeding to avoid slipping and deformation that cause under and over extrusion issues.

Upgrade kit With Optimized Design to fit Mosquito hotends

This is a Bondtech upgrade for the popular Prusa I3 MK3S and MK2.5S that will allow the use of the world-acclaimed Mosquito hotends.

Bondtech Extruder For Prusa i3 MK2.5S & MK3S

This kit contains only the necessary parts to convert your current extruder to our own popular design based upon our BMG (Bondtech Mini Geared) extruder with 3:1 gearing ratio for better precision and resolution together with optimized geometry for the heatsink cooling and professional SLS 3D printed housing.

Product Main Features

This extruder upgrade presents the following main features:

  • Adapted to fit Prusa’s new filament sensor and Mosquito hotends;
  • Includes one Bondtech’s BMG extruder with 3:1 gearing ratio;
  • Optimized geometry for heat-sink cooling;
  • Less moving weight to reduce vibration and ghosting;
  • Professional SLS 3D printed housing and 3 other key parts.

MK3S / MK3S Mosquito, What’s the difference?

This Upgrade Kit is mostly similar to the previous MK3S, with the main difference of having been designed to fit the Mosquito and Mosquito Magnum hotends.
Other differences come from the design changes that include:

  • An optimization of the cooling air channel to focus the airflow on the Mosquito’s heatsink. The channel is narrower.
  • This tighter space is also used to hold the hotend in place during nozzle changes, so the user can change the nozzle with a single hand.
  • The fan shroud was also redesigned to fit the Mosquito hotends.
  • We include in this kit a new part, the Mosquito hotend adapter, 3D printed with SLS.

Prusa’s Heater or Mosquito Heater, What should I use?

The Upgrade is compatible with the thermistor and 40w heater already supplied with the Prusa.
However, you also have the option of using Slice Engineering Mosquito thermistor and 50W heater.
We recommend the more efficient 50W heater for your Mosquito to reach a stable operating temperature faster.

  • If you have a Prusa i3 MK2.5S, buy the 12v Mosquito heater.
  • If you have a Prusa i3 MK3S, you should buy the 24v Mosquito heater.

Updating the Firmware

To use this upgrade in the MK2.5S / MK3S, the E-steps and Z_Max needs to be updated. Check out the latest version of our firmware here.
We are also supplying firmware versions compatible with the use of Mosquito’s thermistor.
If you are using this Mosquito’s component you should use the related firmware.


Community involvement

This is a co-development work with awesome guys in the Prusa Community like Chris Warkocki, Grégorie Saunier (Bear Upgrades), Olof Ogland, Erik Bjorgan, Josh Jones, Kyle Wiehe, Marc Evertz, Matt Harrison, Ocie Ward, Sando Bendig, Vecko Kojchevski (Vecko Extruder), Steven Mölby, and Yuri Delia that have provided excellent feedback and suggestions of how to develop the “perfect” extruder setup for the Prusa series printer. A lot of work has been put in this project and we tried to listen to all the inputs in order to find a solution that can be the best fit to the Prusa I3 MK3S.

Smooth Look
I wore this to an outside wedding and it looked great and I had multiple people compliment me on the suit. It is made of linen so it is a little more casual and comfy than regular suits and works well in the summer or for outdoor events. I am 5'8" and 160lbs and the small fits me well. I would say for the jacket you want it to be a few inches bigger than your actual chest measurement and then choose the correct size for your pant waist.

Pleasantly surprised
When I first ordered this suit, I wasn't sure if I had made the right decision. When I looked at the sizing chart, I was kind of in between sizes. I'm 5'11" and 195 lbs, with a muscular build. Given the size chart, my pant size was more of a medium, and my jacket size was a large. In this case, I decided to go with a medium, and favor the pant size. I'm actually quite glad that I did that, because the pants fit me very nicely. The jacket is a little tight on me, and buttoning it up is probably something I won't be able to do very effectively, but I'd rather have a snug jacket, then loose fitting pants. I like the color quite a bit, and the fabric is quite comfortable. Of course, it needs a steam, so please try not to focus on that too much with the pictures that I posted. Anything made of linen will wrinkle easily, so it will need that type of attention paid to it more often than not. The jacket is very nicely made, and not as thin as I was expecting. As a matter of fact, when I think of linen, I think of a thin garment. This suit has more thickness to it than I anticipated, and I actually appreciate that. It feels more like a business suit, then a leisure suit. I also like the tailoring of the pants, and find them very flattering for my lower body. All in all, I was pleasantly surprised. I only wish I could have had the pants in medium, and the jacket in a large, but given the choice I think I chose wisely.

Class without the price
Size: Large, Color: Burgundy
After purchasing many of the suit offerings on Amazon, Luperty's suit are the best for the price. The adjustable pants makes for a smooth fitting experience, and allow you to breathe when you've clearly eaten to much. The pant length is ideal for a classic suit appearance. If you want a more modern fit you'll have to get them hemmed higher. The vest is form fitting, which is to say not as forgiving as the pants, but will definitely cut a sharper figure. The jacket fits well off the rack for me, albeit the sleeves could be pulled in a bit. I ordered a Large size, which all the pieces fit well for a 5'11", sub 200 lb man. I wouldn't say I'm very in shape, so your milage may very. After buying my first suit from Luperty, I was so impressed that I purchased the rest of the colors as well. My only complaint is that I wish the sleeve lining was more interesting. They all use the same generic white striped fabric. I would have liked to see more variation for each of the different colors. As I have bought all the colors, even the cream color which they no longer offer, I think I can give some insight on which ones work best. 1. Burgundy - This is the best looking one. It's a statement to wear this color of suit. This suit is bold but refined, like a smooth wine. I've gotten the most compliments with this color than any other. It's eye catching and sharp, and you'll feel classy in it. I've actually bought two of these. 2. Dark Grey - This suit is the one you wear to an important board meeting. It's a beautiful charcoal that has a nice sheen to it. A timeless appearance that shows class but muted enough to not take center stage. 3. Cream - Another bold suit, maybe too bold seeing as how they no longer sell it. This suit defines the Miami Vice mafioso look, and it pulls it off nicely. Pairs extremely well with bright pastels. Don't forget to lose the tie and unbutton at least two of the top buttons to get the full effect. 4. Navy Blue - This one's name does it a disservice. The blue is almost at Royal Blue level. The color is definitely striking and can be elevated easily. You might be able to pull this off in a professional setting as well as blue is seen as a more business oriented color, though I believe this is just slightly over the top. However, I like over the top. 5. Light Grey - This one is very light. You wear this one to the same things as the dark grey one, but want to show a bit more character. It strikes me as more of a European color, and maybe that makes it feel more sophisticated. Wearing it with a pocket watch is optional but recommended. 6. Black - This is where we start to decline in color quality. I knows it's black, but I'd like to have seen some more texture, similar to the dark grey. Hopefully you don't have to wear it much given the negative context. 7. Dark Navy - I think I like this one better than the black one, however this one is DARK. I often have to put it right next to my black one to differentiate them, it's that dark. In various lighting you can tell people its a black suit and no one would refute you. Because of this reason I think it's worse than the black. But it makes for the perfect bog standard suit to wear into the office if you need it to. All of these suits are under $100, and often go on sale for less. I cannot recommend them enough for first time suit buyers. As always, remember to open up the vents in the back that are sewn shut, as well as the pockets. As lucky as I am to be able to have these fit almost perfectly, the last step in any suit journey is to have them tailored to you. It might cost as much as this suit, but a $1000 suit off the rack will have nothing on a $100 suit that's been tailored.

Great quality for the price.
Size: Large, Color: Black
All I have to say about this suit is WOW! I lost a good chunk of weight and needed a new suit for an event. Given the price I gave this a shot, and I am really impressed with the quality for the cost. The size is perfect, and the pants are comfortable with an internal elastic that looks and feels nice. The design makes it so the pants don’t slip down with nylon and silk shirts. Looks just as good (if not better) than suits in the $300 price range. I can’t speak for the other colors, but the black suit is exactly what I needed. Let’s see how long the suit lasts!
