I've designed some replacement backing plates for the PLCC to DIP adapter I'm using on my STE.

Here I give you a very quick run down of the design, how to fit them and what to modify for a different PLCC chip.

These are still under test and may not prove to be long-term stable, but they're intended to allow for a bit of 3D printer tolerance issues.

In situ force can be controlled by varying the length paramter. the 'spring constant' can be controlled by varying the curve thickness parameter.
