wiimote grip to replace the B button with a microswitch. I took the grip from the following design: https://www.thingiverse.com/thing:2837943 I resized to fit the wiimote and created a coupler to glue/screw to the battery cover. I make a hole in the battery cover but you can use the B button output. I removed the B button and solder 2 wires that are connected to the microswitch. The microswitch is a 6.5mm x 10mm x 20mm.
