The GoPro Gravity Slider is a custom mount for a GoPro that allows it to shoot footage of an object as it is falling. If you drop the object and the GoPro at the same time, you'll see the whole fall down to the bottom. Then the object will splash or splat or break in some other way.
Or just watch the video below and you'll see what I mean.
Paso 2: Printed parts
There are three pieces for the slider. The two blue pieces were printed on an Afinia 3D Printer and hold the rods in place. The middle piece was printed on an Objet printer, but could've been printed on an Afinia as well.
If you don't have a 3D printer, you can easily make these pieces with some scrap wood and a drill press. Instead of the custom GoPro mount that's automatically included, you can attach a regular GoPro mount onto the wood with the included adhesive.
STL files are included below.
Paso 3: Attach first end cap
The caps are easily attached. Here's the process:
drill pilot holes
place rubber spacers over holes
attach cap with wood screws
Paso 4: Attach second end cap
Attaching the second end cap is just as easy. For alignment, insert the rods before you attach them.
Paso 5: Attach slider
Now that the rods and caps are in place, put the slider mount on the rods. Once it's on you can insert the rods into the bottom mount.
Paso 6: Attach the GoPro
Now it's time to put the GoPro on. Just slide the case with the GoPro in it onto the printed mount and insert the screw for it.
Once that's on, put some padding behind the case and secure the GoPro to the slider with some tape. Here I'm using two small strips of Gorilla tape. This last step helps to keep the camera from rotating on the mount on impact.
