I wanted to try some smaller models.
The Floating Crystal measures 28, 42, 56 mm. I should have gone thicker with the chains, but I was able to print it at this size. There is a built-in support at the bottom of the model. This is the only support I needed. After it's printed, just break it off. There is also a model without the build in support.
The Portal measures 27, 17, 56 mm. Easy print, no supports.
The Golem measures 33, 28, 48mm. No supports, easy print.
