This 5-piece stand organizes several sizes of nail polish and nail files all in a fully rotating, beautiful package. It requires no extra parts to assemble, but sanding tools are recommended to get a smooth spin as well as a little glue to keep acrylic sheets in place. Depending on the 3D printer settings, etc, more or less sanding may be needed to get the correct fit. Made originally as a gift for a friend.1) Print out each of the 3 bases: bottom base, bottom spinner and top base 2) Laser-cut the two acrylic sheets 3) Sand the spin joints and any rough parts for a smooth spin 3) Carefully snap in each acrylic sheet to the appropriate place, making sure holes on the sheet and the base line up 4) Add a dab of glue to hold the sheets in place 5) Stack the bottom base on the bottom spinner, and the top base on the bottom base 6) Try to spin the top or bottom base. If not smooth enough, sand the joints again until rotation meets your expectations 7) Enjoy!
