I used this thermistor (https://makerparts3d.com/products/thermistor-cartridge-3x20mm-and-xh2-54-terminal-1m-cable).  Mounting requires one M3 Roll-In Tnut (https://www.ebay.com/itm/358027552623) and one M3x12mm SHCS (https://boltdepot.com/Product-Details?product=6381).  All links are for reference as these are standard parts.
