With a piece of wood from a craft store and a couple of simple hand tools I built a connection plate that fits into the same tripod I use for my DSLR.
Step 1: Supplies and Tools
GoPro camera (with plastic case)
Tripod with removable plate
GoPro Flat Adhesive Mounts (if your GoPro kit didn't come with flat mounts or you've lost/used up the ones you have, you can find more here)
Light wood stock - I used 1/4" (0.6cm) thick stock
Paint and Paint Brush
I don't own many tools and I was able to complete the project with the tools listed below.
Miter Box & Saw
Step 2: The Underside
Using the removable plate for reference, cut a piece of wood to fit inside the top of your tripod. I started with a piece of wood cut to the exact same size as the bottom of the plate mount and ended up sanding it a bit to get just the right fit.
Test the fit of the piece you cut by placing it inside the tripod stand.
The plate for my tripod has two angled ends to allow the plate to be removed or set/clamped in place for a secure fit. I cut one side at a 45 degree angle. After testing the fit and how everything sits in the tripod I decide to not angle cut the opposite end of the wood piece.
Step 3: The Topside
Using a bit of wood glue, I attach the smaller piece of wood to the newly cut larger piece. Pay attention to the orientation of the trimmed underside block when gluing in place. Clamp the piece together until the glue has set.
Step 4: Finishing The Wood
Step 5: Adding the Adhesive Flat Mount
Step 6: Completed Project
The plastic case attaches to a mounting bracket with a thumb screw. This allows for an addition point of angle control when setting up your camera shot.
A bonus to creating this little tripod plate is that I now have a table-top stand for my GoPro.
