The slide switch is mounted to the inside of the enclosure that's built into the right arm. In order to give it more "grip" so that it is secured in place, we'll bend the two metal sides on the slide switch outward. This will make it so the edges of the switch will have more friction when installed into the enclosure.
Mount Slide Switch
Attach the slide switch adapter to the JST connector (thats wired to the LCD panel) and insert it down into the enclosure, close to the hinge of the frame. Then, plug in the male JST connector from the battery into the female JST connector on the slide switch.
Install Slide Switch
You can use the back side of tweezers to help push the slide switch into the enclosure. There's a little "holder" space for the body of the slide switch. Insert the switch and press it down until the actuator protudes out from the opening. We noticed the thinner Precision Straight Tweezers - Rhino fit perfectly.
The Fine tip straight tweezers have a thicker body and will not fit between the wall and slide switch.
Coil Battery Wires
Leave a small amount of slack on the wire section around the hinge so we can add a small curve to act as stress relief when the arm bends.
Tuck Battery Wires
The remaining wire slack can be tucked inside the arm by using tweezers to gently push the wire between the JST connector and the arm wall.
Next, we'll fit the lid over of the enclosure. Slide the LCD-lid.stl part at an angle and then use your fingernail to gently push the rest of the lid inside the enclosure.
Make Pins for Hinges
You can use a piece of 1.75mm filament or a paperclip to create the pin that holds the arms to the hinges on the frame.
Paperclip pins will be stronger and can withstand more force. Attach the LCD-arm.stl and LCD-bat.stl parts to the frame and insert a paperclip the hold the parts together. Now we can use flat pliers to slightly bend one end of the paperclip to hold the pin inside between the parts. Use flush cutters to size and cut the required length.
When using a piece of filament, heat the ends with the heating element of a soldering iron to create rivets to hold the pins in place.
