Just stuff I downloaded and printed. The dragon I coated in XTC3D clear coat.
The wavy ones were done with vase mode in the slicer so one continuous line and z constantly moving up slightly, but very thin (single layer). Small one took 30min big full size one was about 4hrs. Think the dragon was around 10hrs but could have been a bit more or less it was modelled hollow on the inside so it is easy to print.
Orange and green are petg the black was pla I think but coated in clear coat here as well.
Yah this was actually my first attempt at it. The model is called bloom on thingiverse.com and had a solid version of the model meant to be used with vase mode. From what I gather you just give it a solid model where the outside wall can be printed without supports and then when using vase mode (I did it in prusa slicer might be called spiralize perimeters or something in cura I'm not sure) you basically end up with a very thin but pretty big looking print in little time (it will probably not hold water unless you use a big fat nozzle and or coat it with epoxy or paint)
Prusa slicer or slic3r is open source and can be configured to target different printer profiles/configurations too so I use it for my diy machine as well.
