This is a low poly remix from my burton 425 roadster .
The design is now completed with hardtop.
I used 0.25 layer with a 0.4 nozzle.
8 top fills to prevent sagging.
The axle can be pushed in the slots. I maybe necessary to make the entry a little wider.
Don't carve to much in the middle. Start cutting the corner of the slot. when this fits, push the axle just in.
