I design this 36mm and 33mm key for multiple use.
For example to change car oil filters.
I printed both with BLL X1C 6 walls , 25% infill and Overture PETG black dried for 15h.
It's strong enough!
You can use 100% as well and set higher Z, so increase the height.
If you need help or you want to be printed this parts or customized in different way, just send me a message here on Printables, I can ship worldwide and I promise very good quality prints.
I appreciate if you will give me a donation, so I can bring my ideas forward: https://bmc.link/engineeringprojetcs .
Thank you to support me and happy printing.
