I said that I'd never buy crocs, because they're so ugly. Low and behold, due to covid boredom, I resized and fixed up some parts to make printable crocs. These are actually wearable croc shoes, printed in TPU a95 size 40, US 7.5 men, US 9 women. Made for someone that said she'd also never buy crocs lol.
You still have to make holes if you want to print the seperate strap with it. The sole can be a bit thin at the bottom, hence increasing it a bit in height could provide for better foot support. Also increasing the width could benefit normal/wider feet, as she has small feet. She said that it feels great overall, despite the looks.
Around 320grams of TPU, print time was around 2 days and some spare (probably not worth it, but still did it lol).
ps. you can simply adjust the size by increasing the CM/inch in length in regards to your own measurements. If your build plate isn't big enough, slightly rotate the print and use support.
