Customizable spool holder (prusa i3)

Ok, so I got a new spool of filament which has fins inside the spool's center, so my previous spoolholder couldn't handle it.

So I made a new one, it's basicly same as the old one but instead of of those pins, this has only a hole for a bolt.

And then I turned it into a customizable thing, this one can spawn the older pin-type holders as well as the new one I needed myself.

A work in progress as I try to figure out how that customizer works.
**Edit: I made some changes, lets see how it
