temperature silicone sock designed specifically for Bambu Lab A1 and A1 Mini heating blocks and hotends. A singlepiece cover that improves thermal stability, reduces filament buildup, and makes maintenance faster and easier. Key benefits Keeps heat where it belongs: thermal insulation reduces temperature fluctuations around the heating block for more consistent extrusion and fewer thermal disturbances. Cleaner hotend, less maintenance: prevents filament crumbs and carbonization from sticking to the block, so you spend less time scraping and cleaning. Reduces oozing and stringing: a stable block temperature and reduced convective cooling help minimize ooze during travel moves and long prints. Durable and temperature safe: made from temperature silicone formulated for hotend use; designed to withstand typical 3D printing temperatures. Easy to fit and remove: formfitting design snaps over the heating block for quick installation and removal during maintenance or nozzle changes. Key attributes Compatibility: engineered for Bambu Lab A1 and Bambu Lab A1 Mini heating block and hotend assemblies. Material: temperature silicone designed for repeated use on hotend heating blocks. Quantity: 1 piece included. Fit and form: compact, tightfitting cover molded to match the A1/A1 Mini heating block profile for reliable contact and insulation. Performance: improves thermal stability, reduces external heat loss, and limits filament deposits on the block surface. Practical use cases Long prints and temperature materials: keep the heating block thermally stable during multihour prints or when printing with highertemperature filaments, reducing layer inconsistencies caused by fluctuations. Multipart or multimaterial jobs: reduce ooze and stringing between tool changes or travel moves, improving surface finish and reducing failed print artifacts. Routine maintenance and filament swaps: use the silicone sock to protect the block during filament changes and make postprint cleanup faster by preventing hardened residue accumulation. Notes and care Designed specifically for Bambu Lab A1 and A1 Mini hotends — verify compatibility before . Remove and clean periodically; wipe with a soft cloth or warm water if needed. Avoid sharp tools that could cut the silicone. This simple upgrade provides measurable improvements in hotend cleanliness and thermal performance with a lowcost, easytoinstall silicone cover.
