adapters from all sizes to all sizes

[zeilden]

you could ad only 5 adapters but ad the ability to change the bottom size of the adapter

I'm not sure if it's possible to change radial size using variants.

I'm not entirely sure what you're asking for- do you want a set of parts that have the top end fixed at a specific size e.g. 1.25m but the bottom end variable to any size at all, from 0.625m to 3.75m? I don't really see the value in something like that, as there are enough stack adapters already in the game that make steps from one size to another. If you're wanting a procedural adapter, take a look at the Procedural Parts mod which is entirely configurable to whatever sizes you want, although the build process is considerably different to stock KSP so may take some getting used to.

If you don't want a procedural part, try Missing History for some useful additions to Making History (and it turns the FL-A10 into a fuel tank which is useful for smaller rockets); Near Future Launch Vehicles for some oversized rocket parts in 5m and 7.5m sizes, which also contain engine adapters that also double as stack adapters; and ReStock+ adds some extra adapters in the 1.25m-1.875m-2.5m brackets too (and also makes most of Missing History redundant as of ReStock+ v1.0).

Is there something in particular that you don't like about the stock stack adapters?

imaging a MK1 parachute with a adapter to 5m below it.. yeah, this is a good idea, with curved adapters. i support, but the one. i mentioned earlier would be a little useless(but funny).

Okay but it can't be done with only five adapters. We have short adapters, long adapters, adapters with fuel, without fuel... So let's sum it up, one per upper node size (0.625, 1.25, 2.5, 3.75, 5m) times two because fuel, times three because length. I left out mk2 and mk3.

That's 30. Right, some of them don't exist, like 5m flat fueled, but my point is, if you're going procedural, make them all like that. Have one with varying sizes. But that won't happen in this game I don't think.

Put a fairing on the big end, and close it inline on the small end.
