https://www.amazon.com/dp/B0DPFMN29N I posted the model I used to mount it on MakerWorld

I use this chamber heater with this mount and this remote mount. It can keep my chamber at 65 during a print. I've made plenty of flawless ASA prints with it and a ruby type nozzle from durozzle. Make sure you print the chamber thermistor mount for the CC1 and use it. Otherwise your reasons will be low because it's touching the steel chassis that is sinking away the heat.
