TPU Barstool feet (commercial grade)

When the replacement feet for my local Pubs barstools became unavailable from the manufacturer, I designed these cushioned but durable replacements. The TPUs properties truly shine in this application.

These pads were designed for barstools that have 1"x1" steel frames. Normally these steel legs would cut through nearly any printable material including TPU. To combat this I created a void for a steel washer to be embedded during the print. The result is a nearly indestructible pad suitable for sustained rugged use. The first prototypes have been in daily use for nearly a year and perform so well that I was asked to produce another 120 for the rest of the stools and then to modify the file to fit the additional 50 dining room chairs.

The key is the steel disc insert. I used a 1.5 inch Zinc plated steel washers I purchased at my local Hardware Store for less than $20/100. The included gcode file contains the proper pause layer to insert the disc.
