First attempt at designing a vase, pretty simple but it is a nice decoration piece with or without flowers. I printed with PLA Cork and looks quite good. I used a 0.6mm nozzle with a layer height of 0.4mm.

I'm uploading two models: 

1. one completely solid so you are able to modify all the model settings like vase mode, walls, etc.
2. The second one has a defined inner wall so you will have a fixed inner volume but can still modify settings of infill and walls.

Upload pictures of your results!

Have fun printing :)
