THIS IS A FULLY PRINTABLE, WORKING, MOVING, GOLF CART PRINT. I wouldn't necessarily recommend scaling down parts either because then the smaller details will probably create problems when trying to print.

Finally fixed this thing. Here's how to print it if you want it:

Print the roof as is, supports aren't necessary but will probably result in a cleaner print.

Print the "Body" file with supports everywhere that you might see fit, you'll need them.

Print the "Axils" file which is where you slide the wheels on and then super glue this part to the bottom of the "body" file.

Print the wheels standing upright, no supports needed.

Slide the wheels onto the axils and then print the pins to super glue inside of the axil's holes to keep the wheels inside.
