All that's left is to glue the sensor to the "handle", a 1 5/8" x 5" piece of acrylic, that seals the bottom of the sensor and lets me hold it in place under water without my arm or hand interfering with the measurement.

I think this is the ultimate PAR meter for the DIYer. Easy to make and cheap.
