What's in the box:
- 1x 32×5.48 mm stainless steel heat-break
- 1x 35.3 mm 2/4 chamfered PTFE tube
We recommend to use thermal paste
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 Bondtech by Olof Ogland
and they adjusted it to its final form during the deep testing they performed on the Prusa Mini.
