With all electrical components fastened to the enclosure base, 22 gauge stranded wire was soldered across all required pins.
A generic velcro ankle strap was ordered on Amazon to fasten the enclosure to the user's ankle. The length and width of the strap were appropriate for the enclosure dimensions and the range of dimensions for a human ankle.
The fit and comfort of the enclosure and strap were excellent. The curved design of the enclosure was comfortable around the ankle, and the velcro grip was strong. However, the strap was thicker than expected, which requires a redesign of the enclosure base and lid.
