About this 3D model
If you want to transfer your Citadel paints to dropper bottles, you can try this. There is a funnel and a support. The funnel is independant so it's easier to wash. Once the two part are stacked it's quite sturdy. I transfered all my Citadel paints to 15ml dropper bottles. This can work to with 20ml bottles, but you might want to scale up a bit before printing.I did a youtube video of me transfering my paints. It's in french, but you can mute and the steps are easy to follow.
