Patio umbrella base glide

These are mounts for glides replacing wheels on patio umbrella bases and allowing them to slide easily on composite deck material. One design is for a square base and the other for a round base.   The square design  uses  one slider pad per corner.  The larger round base uses 8 slider pads in pairs due to the weight.  The slider pads are designed to fit under appliances like fridges and stoves.  

The PETG printed mounts are held in place using silicon.
