Helinox Ball Foot for 17,4mm poles (Chair One XL, Swivel Chair, Sunset Chair, Savanna Chair, Bench One)

Remix of the great model from Peter H with adapted dimensions to replace the original feet on the Helinox chairs with 17.4mm poles. 

In my case they are used on my Swivel chair, but according to Helinox's description they should also fit the following models:
Chair One XL, Swivel Chair, Sunset Chair, Savanna Chair and Bench One

Helinox also offers feet for poor terrain, which can be fitted over the original feet to prevent them from sinking in. These are somewhat expensive and, with their spherical shape, also bulky and do not suit everyone's taste in design.

Peter H's model is much more attractive and also takes up less space during transportation. However, the original feet must be removed!
(The original feet can be loosened by placing a short wooden slat or similar on the foot parallel to the bar, then gripping the slat together with the bar with one hand and then hitting it lightly at the top with a hammer)

I printed the feet with Bambu Lab TPU 95A, gray, with 4 wall lines and 15% infill. 

The TPU makes the chair non-slip and the feet can still deform a little. This results in a very soft sitting feeling and increases the contact surface on soft undergrounds.

Highly recommended upgrade for the chair!

Many thanks to Peter H for the design!

(If, like me, you are a little clumsy and, for whatever reason, pull too hard on the chair leg and end up breaking the plastic part, you will find a replacement part here to reassemble and use the chair.
