Laundry rack foot extension (vacuum robot)

This extension raises the laundry rack by 15 mm, which is sufficient to indicate an obstacle to the robot vacuum cleaner. The clip is designed for a tube diameter of about 16 mm. 

I printed it with PLA, PETG should do the Job even better.

I decided to make it in two parts because the clip is much more stable when printed as shown. Simply glue the parts together.

my print settings: No Support, 0,20mm, 15% Infill
