Looking for a Bondtech MK3S Extruder Upgrade Kit in Australia?

This is the latest generation Bondtech upgrade for the popular Prusa I3 MK3S, with an optimized design achieved with the help of the community.

This kit contains 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.
It is also compatible with the MK2.5S model.

LIGHTWEIGHT BMG (BONDTECH MINI GEARED)

With this version we also lower the moving weight to reduce ghosting and vibrations or to allow increasing the printing speed. 15% of weight saving was achieved.

PRODUCT MAIN FEATURES

This extruder upgrade kit is for the Prusa i3 MK3S, or other Prusa i3 models upgraded to MK3S.
These are its main features:

  • Adapted to fit Prusa’s new filament sensor;
  • 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.

    ADDRESSING 3D PRINTING ISSUES

    The enhanced housing design improves cooling and decreases heat creeping issues that all metal hotends have when printing with PLA. This small enhancement will avoid many clogs.
    The increased push force will drastically reduce slipping, shredding and deformation of the filament avoiding most of the common filament 3D printing issues that start with under and over extrusion.

    UPDATING THE FIRMWARE

    To use this upgrade in the MK3S, the E-steps needs to be updated to 830, as it uses 32-bit micro-stepping. Use this file instead.

    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.

      Colorful and handy
      These are really nice and also inexpensive. The colors are bright and similar to photo. The wrist strap is handy. They fit the appletv control just right. (Snug enough but not hard to take on and off). These help protect against falls and also make it easier to find the controls. No complaints

      Excellent quality. Highly recommended!
      Excellent quality and packaging was very secure and minimal but recyclable! I love the cell of the remote control of silicone skin. Both a nicely vibrant colors and easy to find. The worst straps are seriously heavy duty. That's great for gaming. I didn't need them but the silicone protection is amazing. I have two Apple TVs. The price you can't beat anywhere else. If you've ever dropped an apple remote, you quickly discover that the remote is partially made of glass. They are expensive to replace. Save yourself a headache and get these.

      Prepare to love your Apple remote again!
      This is a must buy for anyone that owns an Appte TV. The remotes are small, and sleek, and slippery. My whole family drops or loses the remote constantly. It was a constant struggle. After slipping on the teal blue silicon sleeve it was like we had a whole new remote. It makes the remote much less slick feeling. Not nearly as easy to drop. The bright blue color makes it super simple to spot in the couch cushions or on the counter. The sleeve provides protection from the all too common drops that happen everyday. It does make the remote slightly thicker, but that isn't a bad thing. It fits in your hand much better and makes operation easier too. Well worth the price and you get two! Totally recommend these.

      Great value, solves a big problem!
      Wow, what a great product, so inexpensive for two, and solved one of my biggest aggravations. This remote fits perfectly over the apple TV remote. The remote is so slippery, black, and it is not designed to be able to tell which way is up. This cover solves every problem. It is no non-stick, I don't lose it anymore. I used to drop it once a day at least - no more dropping the remote. It fits just right, you can easily tell which way is the up. It fits just right, and you can still use every feature of the touch pad, the fast forward, etc. Just right!!! Excellent!!!
