Intervals between turns is the distance centre to cnetre between each turn which cannot be less than the wire diamenter, right?
If the intervals is edge to edge of each turn, then it can be zero.

Even if I plug into 10mm for coil dia. 1.3mm for wire dia. and 0 for gap distance. I still got 10cm, that is still unreasonable.

Just wondering how it is done in quad 303 .

Except for the fact that most 2W cylindrical resistors have steel end
caps, in which case it will be a partially steel cored inductor.

Interval between turns seems to be the distance between the edges of each turn. So if it is a close wound coil the distance is '0'.
Try 'several layers' selection on top. You will get a two layer answer with length of your choice ( 25mm? ).
