NESE 18650 battery holder alignment pins and blocks

thingiverse

You can use these prints as alignment aids to help organize your battery blocks. They only work with the 18650 holder sizes and styles, though. Print as many as you need of each one. It's up to you whether you want to glue them in permanently or leave them unglued for easier disassembly. The last picture shows how these parts can also be used as standoffs to create an air gap for cooling. They are strong enough to align the packs during assembly and bench testing, but do not rely solely on them for securing the packs. I printed these using the recommended NESE cell holder settings, except I changed the infill to 25%. The models come in single or double parts. Printing at least two parts at a time is recommended, especially for the triangle pins. This allows for extra part cooling time and results in better prints. These fit my NESE holders perfectly when printed on the same printer without any filing needed. Depending on your printer, you may need to adjust your print settings or do some minor filing.
