It doesn't seem like it's a common thermometer, but maybe someone out there will find it useful. This holder has a cutout for the clip. The cap goes down to about where the clip starts (Further than what is in the picture)
Was able to print standing tall with a brim (BambuLab X1C), but may be a problem for bed slingers due to it's height.
