Dome Bumper Mold - Threaded Rod Insert

Made a duplicate of this to create an open mold to allow one to insert threaded rods into them - we use these to replace cracked/missing rubber ball feet from our Glidetrack Pro and OmniSlider.

same size as before; just print one of these, flip and tape around the edges fill each sphere with silicon part ways to the top and insert threaded rods into the holes.
