ATF filler hook

A tube for pumping automatic transmission fluid into the inspection port on an AT. Rather than buy the ATF tool kit, I repurposed an old pump sprayer, this accepts the o-ring from the original spray handle wand and inserts into the spray handle.

I used 100% infill to prevent any chance of this breaking off inside the oil pan, but likely can be printed at far less - 30% to 50%
