RC motor Glassing Lid for Mason jar

This lid is a simple remix of the Mason Jar Lid by GBlades.

It adds a simple cutout for wires to pass through.

Part of the process of getting a new brushed RC motor ready to go is glassing the brushes. To do this you run the motor under low power in water. The first time I did this I applied to much power and made a mess. This lid helps limit accidental messes.
