Cliq Chair (or Go chair) replacement feet

The rubber feet on my Go Chair(Cliq) fell apart do to the rocky beaches on our lake. So the chair would just sink through the rocks or sand and it would be unstable. After a few years I contacted Cliq and they ended up giving me a brand new chair because my chair was from before they changed their company name. That didn't solve the problem completely, as I had  completely functional chair that just required new feet. After a while, I finally decided to design my own feet. The best way I thought to go about it was to design the leg then design the foot around that. The mk15 file has a snugger snap fit then the mk16 in case there is any stipulations. I can not guarantee this will work on every Cliq or Go Chair as I do not know if they adjusted their own designs over time. I printed these in PLA but PETG or TPU would work as well.  STEP and SLDPRT files are included. Let me know if there needs to be any drastic changes. Also I will be adding wider version of the foot so it doesn't sink as far into rocks and sand. 

These do go on a certain way. Start by matching up the bottom or the Lower Part of the “U” with the corresponding part on the leg. Then push perpendicular to the leg so the foot slides over the tips or top of the leg. If That doesn't work then try another way.
