Here are some useful tools and some advice to help you to design your battery covers.

The info you need:
 
In order to design the cover accurately, you will need the following data. Your measurements need to be as precise as possible so we recommend using a caliper.
 

 
Even if you lost your cover, you can get the information you need from your device:
 

 
Shape library:
 
In this section, you will find different types of covers, a method to design each type and the tools you will need. Each tool has a small video tutorial associated to it, in the Tutorials section.

Clips and Pins:
 
Here are a few tips to help you to earn some time when designing those parts:
 
  • Make them as thick as you can. The limitation will be the space available in the device.
  • Add filets. It will reinforce the attachment to the cover body.
  • If your part doesn’t fit and you have overhangs on your clips or pins, cleaning the first layer might fix the problem.
  • To test the clip or pin mechanism and position, you can just cut and print a small part of your cover.
