Here I have a Christmas vase for you :) You can use it perfectly to store all kinds of stuff in it or decoratively to put candles or something similar in it.

You can also paint the vase afterwards with suitable pens such as acrylic pens or create a little activity for the children!

Sacle the Model!
I uploaded “only” 1 Model of this Vase. But you can easily scale it up or down in your printer! If you scale it up I would recommend a bigger nozzle!

Increase the wall thickness!
This model is designed to be printed in Vasemode! So there will only be 1 perimeter as a wall.

You can increase the wall thickness in your slicer! So even with a 0,4 mm Nozzle a 0,6 mm Wall should easy be printable!

Chimney Effect: Air cooled!
If you use a real candle (Attention! Never leave burning candles unattended! The risk of fire is simply too great!) you can cut off the blops at the bottom and cool air can now flow through these holes! The warm exhaust air from the candle will automatically draw in the cool ambient air through the holes created. This cools the vase and prevents it from deforming quickly or at all.

Material:
I would recommend to use heat resistant and tough materials like PETG, ASA or others to make it as durable as possible! (I printed all of my prototypes in PLA and tested them)

Maybe Prusament PETGV0 Is a good choice in combination with real candles?

Have fun!
