Freeplay Zero finally done! Pictures and final thoughts

[Flavor]

I do think a dab of hot glue on the bottom corners could work.

I also think that putting a bit of thin foam between the LCD and the FPZ board can be good. It could also be the sort of thick double-stick tape, but if you use that, I would NOT stick it to the LCD and the circuit board. I think we included some foam with the LCD itself. That might be good if you fold it once or twice to get a little more thickness. Just be careful to not put any real pressure points on the LCD. Having the foam compress to add tightness is good. Compressing the foam to the point where it flexes the LCD itself is bad.

You can do it between the LCD and the battery compartment, but that's trickier to do properly.

If you take the back off of the shell (and leave the circuit board screwed down), you might be able to push the LCD "up" and then run a strip of masking tape or something along the bottom of the LCD (sticking it to the LCD and the shell). With your translucent shell, you might see it, though. This is how I would go about adding hot glue, but again that may be noticeable from the front (through the translucent shell).

Otherwise, with the back off, I'd loosen or remove the PCB screws and then slide in a bit of padding/foam/etc between the PCB and LCD. Again, just put in something that will compress when you tighten the screws.

The next thing step you could do is to take some thin double-stick tape (a rather thin strip) and put it around the edges of the LCD area. Then you can drop the LCD back down into place. This should do a good job combined with padding between the LCD and PCB. The goal here wouldn't be to really stick the LCD to the shell but to add just enough adhesive friction to keep it in place when combined with the padding.
