I made this GoPro Boom so I could easily position my GoPro in areas that did not allow for a tripod. This can be used in a number of different areas. I will also be using it to position my GoPro when making time-lapse videos of prints. The Tube Bracket will hold a tube with an OD of 25.4mm and the pin that holds the Tube and Wall brackets together is 8mm in dia. You can use a bolt or in my case use an ink pen. Hope yall find this useful.

30-40%

I started with 35% infill and the parts were way overkill with the Colofabb XT so I then lowered the infill to 15% and they have held up great!
UPDATE: (9/28/16) ~ ~ ~~~~
The infill for the tube bracket can stay low around 20% but I have printed several wall brackets and the more rigid they are the better so I am changing my recommended infill to 30-40%
