Precision Cleaning Needles: Stainless steel needles (typically 0.4 mm) slide into the nozzle tip to break up and push out hardened or burnt filament blockages.
Replacement Nozzles: Spare brass or hardened steel nozzles (such as MK8 sizes) let you swap out worn or permanently clogged parts.
Socket Wrenches & Spanners: Small L-shaped or dedicated socket tools provide safe leverage to remove and tighten hot nozzles without burning your fingers or damaging the heater block.
Anti-Slip Tweezers: Fine-tipped tweezers grab oozing plastic strings or clean out tight spaces around the nozzle tip.
Wire Brushes: Brass or copper brushes scrub burnt residue off the exterior of the nozzle and hotend without scratching softer metals.
