Magnetic Dart to be used with a white board as a target

For an exhibition I needed a safe dart game using a drawing on a white board or flip chart as target.
The idea was to put a magnet on one of the dart designs found in the internet.
This did not work to well because the darts did not fly well and bounced of the white board.
I copied another idea from the internet using a paper tail, and put a "spring" around the magnet to brake it before the magnet reaches the board. This prevents bouncing.
I printed it in PLA with supports, without rafts and/or brims.
I used a neodymium 10 X 5 mm disc magnet. I Glued it with some type of mounting glue.
You have to experiment with several glues to find the right one.
Update: Using this design in reality showed that the spring is very brittle and will break after a few throws. See my other magnetic dart design where I use a foam ring as damping material.

Da Vinci Mini W
Rafts:
No
Supports:
Yes

The spring needs the supports, and is critical.
