I made this so I can use my Railblaza Starport design on the rail of my boat.
I print this with 4 parameter and 45% infill .
I used PETG because the layers bond better than PLA and it has some flexibility that PLA doesn't have.
Supports should not be needed if you orient the parts correctly.
I use this with my Starport model: https://www.printables.com/model/284271-railblaza-starport
I used sanding tape on the clamps to keep the mount from slipping.
It has a very strong grip.
