Safer to touch
Accidentally brushed against the hot end before. This prevents burns effectively.

Essential for K1
This sleeve keeps the heat exactly where it needs to be. My ABS prints have much less warping now.

Good fit
Fits snugly on the heater block. Took a little effort to put on but stays secure.
