Yes, exactly!
On of the thing I was actually also considering was making small tabs that I could use to keep it from sliding side to side and still replaceable. Think that would be wise or just glue the bastard down?
Just use a tiny drop of superglue to hold it in place. It can still be carefully broken out and be replaced this way. The rest is done by string tension.
Nein, nur den Energieverbrauch.
