Look for 4.2 Heatermeter on thingiverse.com . There the sliding back case
Oops, yeah, 4.0Thanks sir. I'll have to look if it's a 4.0 or 4.1 HM I have, 4.0 iirc. This is the one I have semi-permanently attached to my electric smoker. I may just upgrade that to an old Pi3 I have and switch to 2 line on this one.
