I used Cheetah3D for Mac to model these props, Photoshop CC to make textures, and Poser to set them up as props. Some I made in response to specific needs for my Lumen story (like the tissue box and crystal bracelet), while others emerged out of my imagination (like the Messy Fx sets).
I’ve provided the ShareCG links for each freebie set, but they’re also available from Renderosity’s freebies.
See the Q&A page for more info on the apps and tools I use for 3D modeling.
