Working on plans for min diameter 98mm vehicle. What ID does the tube need to be to catch the aft closure? Motor casing on forward end will be screwed in.

Thanks

What do you mean by "catch the aft closure"?

As in slide down the motor case and be stopped by the closure?

If so then just a smidge greater than 98mm ID. Commercial tubes are 99mm/3.9" ID
