This is a cargo barge design based upon the deck plan from the Spelljammer setting for Advanced Dungeons & Dragons 2nd Edition. It is fully modular and uses magnets in all of its accessories to allow quick change of layout.

This includes the base cargo barge deck, two different size cabins (with removeable roof), railings, palisade walls, palisade walls with battlements, a siege weapon turret base, and a ballista that can position 360 degrees.

Designed for 5mm x 2mm magnets (https://smile.amazon.com/gp/product/B09MMWH3WP/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1).

Magnets can be attached with a variety of glues. I have successfully used Elmer's Wood Glue and Aleene's Quick Dry Tacky Glue.

The overall design is not a remix, but it does include a remix of the https://www.thingiverse.com/thing:1836165 ballista for use with the turret base.
