## 3D Printed Case for GEMMA M0

If you're working on a project using the **Adafruit GEMMA M0** , you may want&nbsp;a case to protect it. This simple two piece enclosure can house the PCB and a 150mAh lithium ion polymer battery.&nbsp;

## Portable GEMMA M0

The&nbsp;PCB is secured to two standoffs with M2.5 (6mm long) screws. We have a nice assortment of M2.5 sized nylon screws and nuts that will work well. The case allows access to the microUSB port for powering and programming. A slide switch extension allows you to power the GEMMA M0 on and off. To keep the case (relatively) slim, an opening on the cover lets the JST connector poke through the top. &nbsp;

## Snap Fit Cover

The cover features a "snap fit" lip that locks onto the case, making a fairly durable connection. No screws needed. The cover can be modified to completely cover the GEMMA M0 –&nbsp;So you have the option to remove all of the holes and openings.

## Wire Access

On the sides of the case are two "slits" that&nbsp;allow wires to pass through. If you're wiring sensors, NeoPixels or other components, you can fit the wires into the slits and close the cover. These slits can be removed, or add more. &nbsp;
