Hotend PTFE Tube (43.4mm)
The original PTFE liner inside the heatbreak shrinks or deforms due to thermal cycling, creating a gap where filament collects and hardens. This part restores the tight seal against the nozzle, preventing filament bypass and subsequent clogging. It is a known consumable for this specific printer architecture.

Bondtech Heatbreak for Prusa Mini
This is a permanent engineering solution that replaces the stock heatbreak with a design that moves the PTFE tube further away from the high-heat zone. By eliminating the 'step' where the PTFE tube meets the nozzle, it prevents the thermal expansion/contraction issues that cause the stock unit to clog.
