Files for a pair of mounting points for non-load-bearing poles around the home. These were originally designed to replace the mounting point for a rotating shelf in a kitchen. The brackets come in 2 varieties: A simple mounting point with 2 holes for screws, and a stronger design with 4 holes for screws. 

As designed, the internal diameter is 20mm, external diameter is 24mm (with 2mm thick walls). Screw holes are 4mm in the base of the screw plate, and have a 45-degree edge. The plate itself is 50mm in diameter.

Also included are separate files for both base plates and rings so that they can be easily imported to CAD software and re-sized and re-combined to suit individual needs. Some images include a remixed version.

The original print is PLA and has been functional for ~3 months at the time of upload.
