A Remix of Tefal's SUP to beach ball Valve Adaptor. I had to extend the shaft in order to fit the adaptor to my pump. So check the shaft length first if you want to use that one or Tefal's one.
Since I already printed Tefals I just added (or glued) another ring to it. The file of this thing would be a one print (no glueing needed) and has the (for me missing 4.2mm) already added.
Thanks to Tefal for posting!

Printed laying on the curved side, so that the "inner bar" is standing vertically.
