For my next trick - increased slope angle with only an elastic band.
Loop a rubber band around the batteries and insert as normal.
Place the cover through the band and twist a few times 10-20 half turns to build up a light tension.
Balance on the battery cover curved edge - the rubber band holds the battery cover lug against the casing of the GP2x - it sits there quite nicely.
Available on Ebay shortly for 99p + £1.99 p&p :lol:
Pictures to follow.
