Snow/sand feet for foldable chair with 16 mm dia legs

A friend lost some of the feet of her (Amazon) chair and kept sinking in the soft snow; so made these and they work well.

• Fit 16 mm diameter legs, check yours (note: different diameter than Helinox or REI chairs)
• The feet replaced the existing feet (just slid them off and replaced). 
• The center point provides support on hard ground.
• The wide brim provides support on soft snow or sand.
• The folded legs still fit in the storage pouch with these feet. 

Printing recommendations:

• Print in PETG for water resistance
• Printed in 0.4 mm nozzle / 0.2 mm layer height
• Worked fine with 3 layers , 25% fill
• No support needed
