First off: Thank you Bainite for creating the original dice tower model!

This started with me wanting some randomness to the dice path and thus I made a floor you can add to make the dice take a new route.

So v.1 is without a dragon and v2 is with a dragon (some extra protrusions but shouldn't matter)

There's also an extra level with banners to add some height to the tower (also looks great going under the third level with banners hanging from under the balconies). The banners come from another dice tower project (listed as source).
EDIT: This model gave some users issues with the magnet holes - a remix was posted https://www.thingiverse.com/thing:3004299 and (with the permission of the designer) the file from that remix is now added to this thing as V2 of the middle floor. Thank you daniel8889

EDIT: User Ponymont made a remix with different flags that also cleaned up some geometry issues which should ensure less filament waste during printing! Thank you Ponymont

EDIT: User Jusztin made a remix that fixed some holes that kept appearing in his slicer. I haven't tested this myself and YMMV but I think the two files with "Jusztin" in the filename are your safest bets for the middle floor with and without the dragon!Thank you Jusztin

EDIT: User sansburyb made a remix that fixed some issues that kept appearing with the Justin remix - So if you're interested in the middle floor without a dragon, your best bet is probably the Sansburyb fix. Thank you Sansburyb

Finally there is another top you can add which adds even more height and a "blind" drop of the dice (which would probably induce randomness without adding the extra floor). It's supposed to look like the ruins of an addition to the tower. The original file is hosted on pinshape: https://pinshape.com/items/42734-3d-printed-castles-ruins
