If anyone knows, please respond, because I really need axels for my build

Both Mecabricks and Brickset use the same categories for parts. To find where a part lives, you can go to [url]https://www.brickset.com[/url]. Search for your part and click on the name. On the right side of the screen is a section called Part Details. In here you will find the Category. This is where your part should live here on Mecabricks. Or you can just search for it by name on the top right of the parts bin. Or you can look it up in the parts library. If you open up the part, the folder name will be displayed down at the bottom in the Storage section.

Here's some pictures:

Thank you so much! This helped a lot!
