Oil drain jerrycan cap

Hi ! I designed this replacement cap for my oil drain jerrycan. Thread outer diameter = 27,4mm.

Printed in PETG, it looks to be OK regarding tightness (enough to go to the recycling center without messing the car's trunk). You can re-use the original seal of your broken caps, but in case, i have also made it that you can print in TPU.

Unfortunately designed with square threads, like the original cap, so difficult to print without a support... To have a nice thread, the solution is to tilt it at 45°, with support : three structure, enable interface 50% density, Z-offset of 1 layer thickness (0,16mm for me).
