I found them also easy to trim away from the holes I needed to be clear for the extruder.I cannot see why someone would give these a single star due to their inability to cut holes in the product - after all the product description does not identify a specific 3D printer - they are universal. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Good stuff! Saved my 3d printer a few times! *by D***C on Reviewed in the United States on July 11, 2022* In the past, I have changed my heater block insolation a few times because of poorly fitting, leaking nozzles damaging it with molten, solidifying plastic absorbing into them. The insolation would become a solid, brittle brick of plastic and insolation. This is no fault to the insolation. It was a problem with low quality nozzles.The new insolation is great in itself. It lasts a long time (when not leaked on). It matches my Tina 2/Cadet 3d printer's original material exactly. It is difficult to fit and install, though, needing exact measurements factoring in the thickness, Kapton tape, and a large hole punch. Having insolation like this available has saved my 3d printer more than once! Well worth the money! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Good insulating properties, easy to cut, probably fiberglass not cotton. *by G***F on Reviewed in the United States on February 13, 2018* I bought these to insulate the new print heads  WINSINN MK10 Extruder Hotend Kit .4mm Copper Nozzle M7 Thread Heatbreak with PTFE Teflon - For Wanhao / FlashForge / Creator Etc.  for my FlashForge Creator Pro. So far I'm getting very fast heating times and no evidence of thermal radiation onto the work. Very easy to cut to make the holes for the heads and filament neck too. Be careful if working with bare hands and then touching your eyes or other sensitive areas though. The padding has a fiberglass-like quality. In fact I'm not sure if the "cotton" isn't just fiberglass since that would make more sense for an insulation material after all. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/37787667-wahhing-10pcs-2mm-thick-heater-block-cotton-safe-working-temp](https://www.desertcart.co.th/products/37787667-wahhing-10pcs-2mm-thick-heater-block-cotton-safe-working-temp) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-28*
