With the new ReefDelete the button is quite stiff. It does indeed get better with age but the small button still digs in to the thumb and you can't always see the light to know its on.

This button corrects this with out holding the button on for you so all safety features still work.

This is a simple slip on design which is made to an very tight tolerance so needs flexing to fit. the design is a c-clip so it allows this. it does move but does not really move while using.

The button is engaged by sliding and stays in place. 

This can be printed this with ZERO supports as the button is made in 2 parts and needs a small dab of superglue to assemble. 

This includes a second part that allows for the use of a 12mm rod (commonly used with cheap glass scrapers and sand combers) this currently has 3 positions. 90, 0/180 and 45 degrees. for flexible use. and is press fit of the rod for easy removal and position change.

Due to the more rigid design over my original solution you will need to install this with the battery case removed and use a coin to pry it open to slide over the O-Rings. once on. you can slide it in to place for use. you can replace the battery with out removing the helper by sliding it backwards and unscrewing very quickly.
