GoPro arm Quick n Dirty by RichardSE

Last crawled date: 3 years, 1 month ago

This is more of a concept than a ready-made model. A really quick and dirty GoPro arm. By printing 5 of them flat (or 4 + 1 if you want to use the nut-catcher), the print time is much reduced, as compared to other GoPro arm models I've seen. Also, the orientation gives the part strength, and layer-height is unimportant.
The ones in the pictures are at 0.3mm layer-height.
The center hole is for a M4, and the end holes are for the normal GoPro screws (M5).
I printed with 4 perimeter walls. This give med compression strength at the screw holes. Aside from this, infill as you see fit.
If rigidity is important, superglue (CA) the parts together. Using the M4 as alignment. Just be careful not to spill glue into the sections which intersect with the GoPro mounts.
If rigidity is not so important, simply don't glue it. This gives you flexibility to "bend" the arm.
The thickness of each section is 2.9mm and it fits very well. At least with the prints from my printer.
You need to do some very light sanding on the top of each part. To get any "retract peaks" out. So they fit snugly together, when stacked. The holes should be drilled out using a 4mm and a 5mm drill.
(Sorry, I don't know the imperial drill sizes. You'll work it out).
I suppled the Fusion 360 file as well. So you can modify as you see fit.
