Had difficulty getting double sided tape to stick to the textured surface on the interior of my upright freezer so I modified the base to accommodate two 8X3mm magnets.
Very quick print, less than 10 min.
Magnets holes are sized 0.1mm over to allow for shrinkage, but still should fit snug enough to not need glue.
Probe hole is friction fit and should hold at any angle
No supports required
