Bondtech Heat-break Kit for Prusa Mini
To solve Heat-creep
This Stainless Steel heat-break made by Bondtech for the Prusa Mini addresses and solves the heat-creep issues revealed during the extensive testing we performed on the Prusa Mini.
The adjusted length of the PTFE tube also prevents clogs to form between tube and heat-break.

Included in this kit:
- 1x 32×5.48 mm stainless steel heat-break
- 1x 35.3 mm 2/4 chamfered PTFE tube
- 1x Silver based thermal paste bag 
We recommend to use the included silver based thermal grease to properly fit the Bondtech heat-break in the Mini’s heat-sink.
Notes on twisting the heat-break
To address the heat creep issue the design features a narrower section with thinner walls. When removing the heater block or changing nozzles, caution is required.
Before removing the heater block from the heat-break (or vice versa), heat-up the nozzle, hold the heater block and release some tightening pressure from the nozzle. Let the whole group cool down. After, you can simply unscrew the heat-break from the heater block.
To remove or replace a nozzle, never forget to secure the heater block before twisting the nozzle.
Community Sourced Design
This heat-break design was proposed to us by Olof Ogland and we adjusted it to its final form during the deep testing we performed on the Prusa Mini.
