I’ve never found an elegant solution to add weight to prints. What are your favorite ways? What’s the best cost/weight ratio? Weight to space? Cost/weight/space balance?
I don’t like pouring in sand during the print. It’s too easy for the fans to blow it all over.
I use gyroid infill and leave a hole in the bottom. Then pour in casting plaster after the print is removed from the bed. Let dry and sand smooth.
It’s coarse and rough and irritating and it gets everywhere
I’ve been a fan of making false bottom pieces and using steel wheel weights in them.
Here’s a lamp I made as an example.



I used wheel balancing weights (tiny 5g iron bars) and built them into my prints.
They are pretty cheap and the included adhesive makes it so they don’t rattle around inside if the tolerances of the cavity are not perfect.
Used them in the base of a tall slim model to make it less prone to tipping over.
