Universal Exhaust Pipe Plug (No Supports)

I made this exhaust pipe plug to use when I wash my motorcycle. It will fit exhaust tips from 12mm to 38mm inner diameter. It's modeled to print without supports or brims on its side. The small flat section it sits on does not affect its use.

Printed on Bambu Lab X1C using Overture TPU and liquid glue on the Engineering Plate.

I've included the .3mf that worked for me but I'm sure it can be tweaked to print better and faster. With 30% grid infill it's pretty stiff but works well for dirtbike exhausts. Use less infill if you want more flex.
