This is not my design, but I could not find it on printables.com and the original creator seems to be not active anymore so I wanted to share it with everyone!
Here is the original on thingiversere.com.
Additional shell design can be purchased here to support the original creator of the design!
The model assembles with two of the printed H-Clips and needs no glue. The parts print without the need for supports.
The user re-uploaded this model. The user is not the original author of the model.
