v2 of coin cell battery holder with M2 screw holes..

I've always wanted to use this kind of coin cell battery holder for a project, and finally the time has come..

I am sharing only the battery part since my top secret project is on its early development stages.

Hope you'll find the battery holder useful

Creality

Ender-3 v2

Doesn't Matter

Yes

.2mm

15

No need supports for the v3 base and the lid..

Use support "touching buildplate" only for both v1 and the v2 parts !!
No need for buildplate adhesion..

The Orange parts in the photos are made of ABS filament which are also printed fine.

With some filament brands (such as esun) the lid part needed some fine file tool work for a perfect fit.
