Extra large walking stick foot

After seeing my elderly mother struggle with her walking stick falling over all the time, despite having been fitted with a commercial larger foot, I designed and printed this extra large foot for her.The foot has a diameter of 140mm. The print in the pictures is printed in Teacbears TPU with an 0.6mm nozzle. I have also printed it with a 0.4mm nozzle and the results are very similar. Due to the slow print speeds of TPU filament, the print takes 10-11 hours on my P1S.The foot is designed for walking sticks with a diameter of 19mm.
