Accidentally tossed the insert for my trash can mistaking it for a failed print, so I created a replacement. This one is much sturdier and a better fit than the original which was very warped and barely fit to begin with. This is designed to specifically fit Sooyee 14L (3.7 gal) trash can (amazon link). If your trash can is rectangular and matches the following dimensions: 10"L x 6.8"W x 13.5"H this it should work for you, if not I've included the STEP file so you can modify to fit yours.
