This is another use for recycled wooden tea/coffee stirrers
I find it easier to work in a smaller scale, glue them and clamp them together.
When these have set, then glue them all together and clamp
Glue the center sticks together and mark where the nut is going to be situated.
Cut the space using a small hacksaw or coping saw then sand to get a nice clean fit.
When the glue has set, sand down the top and bottom of both layers to allow a clean joint between the top and bottom layers
Measure the uprights and cut so they are oversize. The uprights can be cut to size later.
Glue the uprights to the base and clamp.
**Make sure that you fit the uprights around the camera lens**
When the glue set, I added another layer to the uprights, both front and back.
Cut to size and sand the whole unit down until the edges are smooth.
Fit to the tripod and enjoy your photography and avoid taking pictures of yourself with the camera at arms length!
