Summary

This is a model of Canon NB-11L battery, 3 variants included;

• Dummy
• Open
• Closed

Dummy is just a dummy modeled after taking measurement of the actual battery itself. The other two model; ‘open’ and ‘closed’ variants are meant for external power.

Open variant are easier to print but the wire may tangle inside your camera's battery compartment. Closed variant meant to encase everything.

The Closed variant need to do a bit of extra work as follows;

1. Print the “dowel” first.
2. Cut nickel strips to sizes.
3. Solder your desired wire length to one end of it.
4. Wrap 2 loops around the dowel's designated channel.
5. Make sure there are “pause & park print head away” before closing the top area of the battery.
6. Place Dowel that you made in step 4.
7. There may by resistance, this is intentional to reduce plays inside.
8. Make sure the wire will not get caught with the hot print head upon resuming the print job.

You may need to optimize overhang angle for the “closed” variant
