I liked the original model, but it had a flap that needed to be cut, I have fixed that. I have also added holes for M4 screws that can be used to create different add-ons to it. 

No supports needed!

Do not recommend printing this out of the PET-G it sticks to itself. I have used Nylon with CF, and it works awesome.

Distance in between of the holes is 15 mm on center of the hole.
