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.

Solid Protection

Does exactly what it says. Protects the hotend well. There was a slight silicone smell at first but it went away quickly.
