Pump adapter (embout pompe) mini Boston for kayak ITIWIT seat

thingiverse

Here's a self made adapter for air pumps to inflate the seat of an ITIWIT kayak's seat, which was missing when we bought it. Tolerances were calculated for a thight mounting and it worked. If it's too tight, you can scratch some material to help it fitting or you could just heat the PLA and then put it in your pump: Heat deformation will make this adapter perfect. Have a good time doing kayak!
