Poor Man’s Caliper Upgrade! by JacobMakes
A simple conversion from button batteries to AAA batteries that are less expensive, you can also use rechargeable batteries that reduce your environmental impact!
Update 1: Slots added to make it easier to remove battery
You will Need:
1 Pen Spring
1 Triple A battery
2 four inch (10 cm) Lengths of wire (preferably 1 red, 1 black)
1 Hot Glue gun+glue or Epoxy/super glue
1 Soldering iron/ solder (I have heard of attaching wire with hot glue so this may not be necessary)
2- Strip both ends of the red (positive) wire. You will need about .5 inches (~ 1 cm).
3- Solder/attach the red (positive) wire onto the positive terminal. It should be a strip of metal on either the side or the top of the old battery box (refer to the last picture)
4- Strip both ends of the black (negative wire. You will need about .5 inches (~ 1 cm)
3- Solder/attach the black wire to the negative terminal. It should be a strip of metal on the bottom of the old battery box (refer to the last picture)
4- Solder/attach the black (negative) wire to the pen spring
5- Hot glue/ attach the pen spring and the black (negative) wire to the large hole on the 3d printed part. Refer to picture 4 and 5. This will be the negative terminal.
6- Bend the stripped end of the red (positive) wire at a 90 degree angle and insert into the small hole on the 3d printed part.
7- Glue/attach the red (positive) wire on the outside of the part to the printed part. Refer to picture 3.
7- Spread the stripped portion of the red (positive) wire into a broom shape. This will achieve better contact with the positive end of the battery
8- Fold the red (positive) wire down so that it is flush with the battery box. Refer to picture 6.
9- Glue/ Attach the box to the calipers. It does not really matter where as long as the location foes not affect the functionality
10- Place the AAA battery inside the box, negative terminal to spring, positive terminal to wire
11- Take a picture! and post it here!
12- Improve on my design! I’m always looking for new ways of doing things, show me what you got!
