GoPro Hero 3/4 360 Spherical Mount / Rig V2 Remix

thingiverse

This remix of martin19791121's design (http://www.thingiverse.com/thing:1257407) is my own creation, marking my first contribution to Thingiverse. I believed his design was the best available for a 360 video rig here on this platform, but after building it, I found several things that needed changing and adding. Here's a list of those changes: I redesigned the brackets so no screw was necessary. Changing batteries in the field took too much time when recording videos with the original setup. My new brackets allow me to replace all six batteries within four minutes. Due to the new bracket design, I reinforced the tab/slot where the bracket hinges in. The original style tab/slot broke because there's a bit more pressure applied when snapping the top of the bracket in and out (this isn't shown in the photo but is included in the stl files). I designed lens caps for the GoPros and added a spot on the GoPro holder to snap the cap onto while recording, preventing it from getting misplaced. However, due to the layout of this rig, the top three cameras have their lens cap holders in one location, and the bottom three cameras have them in another. So, you'll need to print three of each type. I widened the slot where the Wi-Fi button is for better grip when pulling it out of the holder and changed the record button area from a slot to a hole. I also modified how I mount the rig to a pole. No modification was necessary to the cube itself, but instead of placing a 1/4"20 nut in the center chamber, I added a 3" bolt to the mix. The nut was threaded about an inch up the bolt, and then the whole bolt/nut combination was slid into the chamber, leaving half an inch of thread sticking out the bottom, which was then screwed into an adapter. This adds much more rigidity to the entire setup. Hardware required: 24 x size 4 wood screws - 1/2" long 1 x 1/4"20 hex head bolt - 3" long (optional but recommended) 1 x 1/4"20 nut Print Settings: Printer: Davinci 1.0 Pro Rafts: No Supports: No Resolution:.3 Infill: 30% Notes: This design is only suitable for ABS. The brackets would be too brittle with PLA. I'm scaling up the files to 101.5% for a good fit due to ABS shrinkage. Your printer/filament may produce slightly different results, so do a test print of one of the GoPro holders to ensure you get a nice fit and apply that scale to the rest when printing! Filament: Matter Hackers ABS Pro Extruder temp: 230 C (lens caps and brackets were printed at 215-220 C due to being small parts...the excessive heat @ 230 C caused melting/stringing) Bed Temp: 90 C (the max for my printer) Speed: 15 mm/s Infill: 30% on cube and GoPro holders, 100% on lens caps and brackets Brim: 10 mm (no brim on lens caps or brackets) Shell Thickness: Normal: 3 layers. Top surface: 4 layers. Bottom Surface: 4 layers. (I did 3 and 4 layers so that the walls of the camera holders were solid without having to do 100% infill) Bed adhesion: 3M Blue Painter's Tape with a layer of ABS slurry painted on. I added two versions of the cube and GoPro holders. One version is normal, but the alternate has a .6 mm (h) x 5 mm (w) brim. Then I add a 10 mm brim in the print software. This has given me great results with hardly any noticeable warping. There are two versions of everything except brackets and caps - one with brim and one without brim. You decide which to print. What you need is three 'top' camera holders, three 'bottom' camera holders, six brackets, and six lens caps. How I Designed This: I modified the original files in SketchUp and tested them in netfabb Basic (repairing them when necessary).
