It can be a bit painful to get hold of, but I’ve been experimenting with micro-suction sheets, which allows you to “stick” things down to smooth surfaces, without adhesives (the material surface is full of tiny pores that act as millions of mini suctions cups). And allows you to easily remove, and re-stick them later without leaving any goop behind.

It’s a nice way to stop these types of 3D prints from sliding around in surfaces, without having to resort to weights or lead shot, which it way more painful to integrate that you would expect.
