I am attempting to get better at my stand making.

These are still meant for lightweight items but were built to more standard sizes.

Because of their collapsible nature, there connection isn't super strong. You can leave it like this so they can be easily taken apart or glue them together to make them more sturdy. Please be aware that where they connect is NOT strong, but they can still be used for lightweight items such as photos and HueForge pieces. Third image shows how the parts of the stand are not too sturdy and can come apart.

Small (4") is designed for items that are 3" - 5" tall.

Medium (5") is designed for items that are 5" - 7" tall.

Large (6") is designed for items that are 7" - 8" tall.

If you need a stand for something smaller than this, I do have an original simple small stand: https://makerworld.com/en/models/127285#profileId-137710 

Smallest stand is shown holding my rose HueForge image which is 4" squared to give you an idea of size/scale. Rose: https://makerworld.com/en/models/145964#profileId-158877

Again, items on the stands should be LIGHTWEIGHT! Not designed for heavy frames.
