Are you making your own project and need just a few extra rolling ball sculpture parts to complete or compliment your ball run? Then you are at the right place.
I can make elements and lifts that are screwed to a wall and attach to your own tracks. See below a few examples of screw-on chain lifts.
The only elements I have made that screwed onto a wall were for the Elementary Opening credits. But! I can make anything you have seen on my youtube channel to be build as just one element that screws to a wall, or otherwise attaches to your project however you need.
The bottom video shows the elements used in the Elementary opening credits as their raw stand-alone pieces.
