All parts of the chair before assembled into the chair
FAILURES....
need to be 90 degree, achieved by v cut
the gap is to wide to roll over, need to be in curve
the heat gun technique is not really nice for this part, should be a v cut.. looks neater..
cut too deep!
the chair height is too tall, needs to reduce a little bit more.. see my feet is hanging, they aren't touching the ground.
there's a failure in the slotting part in the front.. need to rethink how to slot that part correctly
