I have attached 5 images (hopefully this is allowed).
1a) TOP VIEW: This shows the slide groove widened to 140mm for the 3DWorld mount. There is just enough room on the Regal to do this. I also added an indent for easier access when pulling out the mount.
1b) BOTTOM VIEW: This shows the addition of a tripod mount and radio knobs to adjust for the different mounts. The knobs are available as this website: http://www.active123.com/543742-Pointer-Knob-Pkg2-Prodview.html
1c) This shows a groove in the bottom of the tripod adapter to set the bottom distance for the 3DWorld mounts.
1d) The knobs rotated for 3DWorld Mounts. Essentially, the knobs turn out of the way so the plastic mounts drop lower
1e) Position for cardboard mounts. The knobs block the mount from getting too deep.
Hope this makes sense. Let me know if the pictures aren't attached and I'll try another way.
Thanks, Sam
