Oh and the reason I don’t just join them together is because I resin print the gargoyle and FDM print the columns

Your solution is perfect. Mesh mixer is free to download and works with my old windows which I won’t upgrade. in mesh mixer you can superpose 2 objects and delete everywhere they touch, removing from the column the intersection where the gargoyle fits in atop the column. but again, your magnet solution is probably even better in many ways.

Thanks Ryan! Thanks to you, I managed to get the Gargoyle - it's neat atop those columns, which i meshmixed to boolean-difference with the gargoyle base, so they click into each other. But the firepit is just way out of my price range, infortunately and i can't get it in isolation. Oh well.

Beautiful. Can you please point me in the direction to find the stl files of the gargoyle and brazier that you put atop your columns? thank you very much
