1. The closer the distance between the nozzle and the bed (Z offset value) is,
the more the first layer is pressed, such as the elephant's foot.
   
Parts with round or spline holes on the bottom are smaller in size
and can be affected when assembling.

2. If you assemble two parts, they can be stiff, moderate or loose.
   Especially when you finish your first assembly after printing, they are often very stiff.
   If you try to insert and remove several times, most of them get a little better.
   But if the two parts are barely inserted
or you need too much force when you assemble,
there is a problem with the printing quality.
