14. Battery Holder (BT1): Before we install the battery holder we need to slightly modify the screw 

holes to allow them to better accept the screws. 

a.  Use the tip of your X-Acto knife to gently flare out the ends of the screw holes just a little bit 

(before and after photo). To pre-thread the holes, use a #2 Phillips screw driver to drive an 
M3 screw into each hole. Make sure the screws go in straight. Remove the screws.
