The adhesive black rubber square that comes pre-applied to the bottom of this hotplate doesn't adhere well to it, since the mounting screws of the internal PCB protrude a bit.

This alternative bottom plate solves the problem by letting you use your own double-sided tape; depending on its thickness you may want to print the flat (1-2mm) or the sculpted (<1mm) version. If you saved the original cover you can always reapply it for an extra anti-slip effect.

You will find this 56x56mm hot plate under various names: GDCHP, PD65, G3061, and probably others. It may also be marketed as MHP30, but it's most probably just a clone that piggybacks off the name of the real Miniware product.

For some more technical info and a better PID tune, see here. I'd also experiment with halving the P term to get a slower temperature raise and lessen the bowing of the plate.
