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.
We recommend to use thermal paste to properly fit the Bondtech heat-break in the Mini’s heat-sink.
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.
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.
