Perfect Fit for U1
This sleeve fits snugly over the hotend. It really helps keep the heat contained and protects against dust. Installation was straightforward.

Good Quality Material
The silicone feels durable and heat resistant. It was a bit tight to put on initially but settled in after the first print.
