I modeled this thermometer spool when the ones I bought didn't come with one, despite it being shown on the box! Wasn't happy with the ones that have the probe exposed.

While it's made for this particular BFOUR thermometer, (12mm diameter, 142.5mm long, not including the little 3.3mm screw at the top) I'm sure it can be sliced and/or resized for other probes or cables.
The lead is 106cm including the plug (8mm), and is meant to wind clockwise. The plug slides in from the top with only a bit of resistance.
A thin bead of CA or plastic model glue will do, and the tolerance between the pieces should be enough for most printers.
