Imagine having the ability to hang your extra/any vinyl record up without any sticking out pieces of the mount. Well, I create different sized pieces that you can simply stick onto the middle of the back of your vinyls, nail a nail in the location you would like, and finally place the mount onto the nail and let it hang. Its different sizes gives it the ability to float off the wall at any distance away.**Step-by-step on how to attach the holder to the underside of the table- **First, print the piece(s). Then take the print and put double-sided tape on the back/chosen back of the vinyl (MAKE SURE TO ALIGN IT PROPERLY!!). Nail a nail in the chosen location or even just stick the mounted vinyl on the wall. Finally place the vinyl on the nail, if put one, and enjoy.I would print it at a whole range of 10% - 12% infill density. It will be firm but not too heavy for the (way of attaching the holder) under the table.
