5X High Precision 3D Printer Heater Block Silicone Cover Thermal Protection Socks Compatible with V6 PT100 Heated Block hotend and Titan Aero Extruder

Extremely high quality, fit better than ED3 socks.

These are really well made. Nice sharp corners to hold onto the heater block and ... They shipped with a block of open cell foam in each where the heater block would be to hold the shape during shipping.Very well thought out.

Purchased these to replace a torn sock that got stuck on my heat block that leaked some filament. This sock fit perfectly on my V6 standard style block. Time will tell if it holds up, but it seemed to be a perfect fit. Now I have extras when needed.

The silicon colour is vibrant and quite thick, nice retaining tabs hold it securely in place. There are no defects in the silicon and they feel very good to the touch. These are to me better than the original ones that came with my Hotend.

Silicone soften after long exposure to the heat, come off and ruin prints

It's not worth my time to return it, but I only received three of the promised five covers which made me sad.

I've gone through two of them already. This is a must have.

Items fit and were as advertised.
